A criterion-by-criterion audit of four party manifestos, read against a locked rubric that scores silence as well as substance.
After full audit and incumbency reality check. Scores reflect specificity, mechanism, costing, and accountability. Silence is scored, not neutral.
Darker shades mean stronger commitment with mechanism, costing, and accountability. Lighter shades mean the criterion is under-addressed.
| Criterion | DMK | AIADMK | TVK | NTK |
|---|---|---|---|---|
| 01Welfare substance & conditionality | 5 | 4 | 4 | 3 |
| 02Caste, reservation, social justice | 4 | 3 | 4 | 4 |
| 03Fiscal credibility & centre-state finance | 3 | 3 | 3 | 2 |
| 04Federalism, language, identity | 5 | 3 | 4 | 5 |
| 05Governance & accountability | 4 | 2 | 3 | 4 |

| 08Health infrastructure & public health | 4 | 2 | 3 | 3 |
| 09Education & student welfare | 4 | 3 | 3 | 2 |
| Total / 45 | 35 | 25 | 30 | 29 |
Each axis is one criterion. Each polygon is one party. Where a party extends toward the outer ring, it is strong. Where it collapses inward, it is silent.
Four manifestos, one state, one political moment. The scorecard tells you who is most rigorous. This panel tells you who is most original, who borrows from whom, and where the political centre is converging.
Reading the four documents side by side, the structural pattern is unmistakable. TVK, which released last, is built substantially on the DMK welfare-federalism template with a cultural overlay. NTK stands apart on ideological grounds that no other party shares. AIADMK and DMK converge on everything Dravidian, diverge on everything else.
Where two manifestos substantially agree on direction and mechanism.
Monthly women's cash transfer (Rs 2,500 vs Rs 2,000), free bus travel expansion, subsidised gas cylinders, girls' education stipend, Super App architecture for government services, 70% state GST share demand, NEET abolition, two-language policy, Education to State List, caste-wise census, SC sub-budget ring-fencing, rural housing expansion. The scheme names differ. The policy architecture is near-identical.
Both support caste-wise census, both defend the two-language policy, both demand Education and Medicine moved from the Concurrent to the State List, both insist on Tamil in the Madras High Court, both protect the 7.5% quota for government school students (AIADMK proposes raising to 10%). Where they diverge is fiscal posture, welfare ambition, and the delivered-record debate.
Identical MSP numbers for paddy at Rs 3,500 per quintal and sugarcane at Rs 4,500 per tonne. Both support Sachar Committee implementation. Both commit to cess and surcharge inclusion in the divisible pool. Beyond agricultural pricing and minority representation mechanics, the overlap is thin.
Both oppose the three-language policy. Both demand Governor office reform. Both invoke Ambedkar. DMK claims the Periyarist Dravidian tradition as a founding intellectual anchor; NTK pointedly excludes Periyar, drawing instead from Bharati, Bharathidasan, and Tamil nationalist lineages. The welfare architecture, fiscal posture, and governance design are almost entirely different. DMK's Dravidian welfarism and NTK's Tamil nationalism route through different intellectual lineages and end at different structural destinations.
Both invoke Tamil cultural pride and historical grievance. Both claim Kamarajar and Tamil antiquity. Under the surface the parties part ways: TVK builds on Dravidian welfare institutions, NTK replaces TAHDCO with the Ayodhidasar Foundation and demands a separate state constitution. Shared aesthetics, different architectures.
The thinnest overlap pair in the matrix. AIADMK works within the Dravidian welfarism consensus. NTK rejects Dravidian identity itself as a historical fabrication. The two manifestos do not share ideological premises, let alone policy mechanisms.
How distinctive is each manifesto against the other three combined?
A note on framing. Similarity does not prove borrowing. DMK and AIADMK landing on the identical Rs 2,000 figure for monthly women's cash transfers, with TVK pitched Rs 500 above at Rs 2,500, may reflect shared fiscal arithmetic, shared political economy, or shared policy-advisor networks circulating through Tamil Nadu's ecosystem rather than direct copying. What the pattern does prove is that policy originality is not the defining feature of this election. The political centre has converged. Rigour and delivery record are what distinguish the four manifestos.
Four manifestos, one state, one moment. The goal of this audit is not to pick a winner but to show what each party has actually put in writing, and what each has chosen to leave out.
Each of the nine criteria is scored on a 0 to 5 scale. A zero means the manifesto is silent or contradictory on that theme. A five means the manifesto commits to a named programme with a mechanism, a costing, a timeline, and an accountability provision. The anchors in between are commitment without mechanism at 2, commitment with mechanism at 3, and commitment with mechanism plus costing or timeline at 4.
Scores are derived from the original Tamil and English manifesto texts. Where a party made a specific numerical commitment, that number is cited. Where a party was silent on a criterion, the silence is scored. The rubric treats absence as information, not as neutral ground.
The incumbency reality check applies to DMK only. The party has held office from 2021 to 2026 and its 2026 manifesto continues schemes launched during this term. Where the incumbent's delivery record is materially weaker than its 2021 promises, the corresponding 2026 criterion is adjusted downward. This adjustment is explicit in the fiscal and environment criteria.
A note on what this scorecard is not. It is not a political endorsement. It is not a forecast of the election outcome. A manifesto score reflects the document, not the campaign, not the candidates, not the voter base. Treat the number as one input among many.
Monthly transfers, household benefits, safety-net architecture, and how specifically each party has named the beneficiary, the amount, and the mechanism.
The most architected welfare stack of the four. Kalaignar Magalir Urimai Thogai rising from Rs 1,000 to Rs 2,000 per month, Illatharasi Rs 8,000 appliance coupon for non-income-tax-paying families, Puthumai Penn and Tamil Pudhalvan higher education stipends rising to Rs 1,500 per month, Rs 2 lakh crore of SHG credit over five years across five lakh groups, Rs 5 lakh startup loans for three lakh rural women entrepreneurs, marriage assistance of Rs 5 lakh to Rs 10 lakh for children of deceased government employees, government employee marriage advance raised from Rs 10,000 to Rs 5 lakh. Each component names the amount, the beneficiary criterion, and the delivery channel. Most have been running for at least two years and the 2026 manifesto commits to expansion rather than introduction.
Named commitments with per-unit amounts: Rs 10,000 family assistance under the Amma Illam scheme, Kula Vilakku raised to Rs 2,000, Amma two-wheeler at Rs 25,000 subsidy, 150-day rural employment guarantee, Rs 2,000 senior citizen pension, Thalikku Thangam marriage scheme continuation. The architecture is recognisable and costable at unit level. Aggregate fiscal envelope is absent and the delivery mechanism for some promises leans on reopening schemes that were discontinued post-2021.
Madhippumigu Magalir Thittam delivers Rs 2,500 monthly to every female head of household until age 60. Annapoorani Super Six covers six gas cylinders per year. Vetri Payanam extends free bus travel to all state buses, not just selected routes. Anaivarum Seer provides 8 grams of gold plus a silk saree to brides in under-Rs 5-lakh-income families. Thaai Maaman Seer Pettagam gives a gold ring plus an essentials kit to every child born in a government hospital. Kamarajar Kalvi Urithithogai puts Rs 15,000 per year into the mother's bank account for each child in classes 1 to 12. Widow and supportless women receive Rs 8,000 per month. Dense unit-level costing throughout. No aggregate fiscal envelope, which keeps it from a 5.
Strong on architecture, thin on unit-level rupee figures. Dedicated ministry for children and elderly, 5% reservation for differently-abled in local-body posts, Anbuchchoolai elderly care homes with 24-hour staffing, lifetime travel pass for over-65s, simplified block-level enrolment for unorganised workers replacing the current district-level process, direct bank transfer of pension without intermediaries, free gender reassignment surgery and a dedicated trans hospital in Trichy, farmer pension for over-60 cultivators, marriage assistance inter-category parity. The transgender welfare architecture is the most substantive of the four manifestos. What holds it at 3 is the absence of named monthly cash transfers with specific amounts.
DMK leads because it is defending a delivered record and building on it. TVK and AIADMK are close behind with rich unit-level costing but thinner architectural ambition. NTK has the most thoughtful welfare-institution redesign but the lightest unit-level numbers.
Caste-wise census, sub-reservation within OBC, SC and ST architecture, land restoration, and how each party treats the history of structural exclusion.
Caste-wise census commitment linked to representation adjustment, 27% OBC reservation defence, MBC sub-categorisation from 25% to 31%, state reservation policy applied to medical seats including All India Quota reform, Ayothidasar housing development, dedicated SC and ST commission, expanded tribal residential schools, forest rights continuation. Solid commitment with mechanism. Does not go as far as Panjami land restoration and lacks the explicit intersectional OBC-women sub-reservation that would push it to a 5.
Supports caste-wise census, Adi Dravidar TAHDCO loan waiver, SC temple construction fund raised from Rs 2.5 lakh to Rs 5 lakh, 5% reservation in HR&CE shops for differently-abled, dedicated Boyar and Vishwakarma welfare boards, 1% ex-servicemen quota, special schools for intellectual disability. Named commitments with mechanism, lighter on structural redesign than DMK or TVK.
Caste-wise proportional representation explicitly committed. SC and ST sub-budget strictly ring-fenced to community development. Rs 40,000 annual scholarship for SC and ST students in professional courses. TAHDCO loan waiver. Permanent housing with patta for all SC and ST families. Dedicated atrocity-prevention police wing under each District Superintendent. Sachar Committee recommendations implementation. Waqf-funded minority women's colleges. Strong architecture. Does not propose Panjami land restoration or the TAHDCO replacement that NTK proposes.
Proposes renaming Adi Dravidar to Adi Tamilar by law. Panjami land restoration: the 12 lakh ground of land granted to oppressed communities by the 1891 colonial order is to be identified, recovered, and returned. Temple land audit and redistribution to tribal communities. SC sub-plan fund ring-fenced at population-share percentage. TAHDCO replaced by a new Ayodhidasar Foundation. Caste-violence victims designated as Social Justice Martyrs with compensation and state jobs for families. OBC women's sub-reservation. Common cremation grounds to end caste-based separation. Ideologically the most aggressive redesign, mechanism-rich, costing absent.
DMK, TVK, and NTK cluster together at or near 4 because all three treat social justice as architectural rather than symbolic. AIADMK addresses the same themes but with lighter mechanism. NTK's Panjami land restoration and TAHDCO replacement are unique and would be a 5 with costing attached.
How each manifesto engages Tamil Nadu's revenue deficit, debt position, 16th Finance Commission dynamics, and the GST divisible pool.
Explicit demand to raise the state's GST share from 50% to 70%. Separate financial statement for agriculture with a Rs 1,94,076 crore envelope. Opposition to the unilateral edge of GST. Demand to scrap national entrance examinations for higher education. Engagement with 16th Finance Commission cycle is named. What pulls the score down after the incumbency check is the absence of any direct acknowledgement of Tamil Nadu's revenue deficit, debt-to-GSDP above 26%, or a plan to address these over the next five years. The manifesto treats the fiscal constraint as a centre-imposed injustice rather than a state-level responsibility.
Names the decline of Tamil Nadu's devolution share since the 12th Finance Commission with analytical specificity. Demands inclusion of cess and surcharge in the divisible pool. Demands transfer of Education and Medicine from the Concurrent to the State List. Attacks DMK on the state's debt position (Rs 1,25,000 per capita debt figure cited). Strong federalism critique, no costing for its own welfare promises, no engagement with what AIADMK's own 2016 to 2021 record looked like on the same fiscal metrics.
Demands the same 70% state GST share that DMK demands. Commits to a Supreme Court legal committee to litigate Tamil Nadu's share from the Centre. Produces an annual 'Union Government Injustice Report' documenting shortfalls. Opposes delimitation and opposes one-nation-one-election. Commitment plus mechanism. What is absent is any aggregate fiscal envelope for TVK's own extensive welfare promises or any acknowledgement of how these would be financed against the state's existing deficit.
Most ambitious demand in the set: 75% state share of all taxes collected in Tamil Nadu, going further than the 70% DMK and TVK demand. Caste-wise proportional fiscal redistribution stance. Beyond these stances the fiscal mechanism is thin. No costing for the manifesto's extensive welfare, health, and education programmes. The document treats fiscal detail as a centre-state political question rather than a state-budgeting question.
This is the weakest criterion for all four parties and the clearest illustration of what the rubric measures. Every manifesto has dense welfare commitments. None has a credible plan for funding them against Tamil Nadu's real fiscal position. DMK's incumbency means it cannot hide from this.
Position on the three-language policy, NEET, delimitation, one-nation-one-election, Governor office, classical Tamil status, and the wider question of who speaks for Tamil political identity.
Classical Tamil promotion with Semmozhi Manadu, named opposition to the new education policy and the three-language formula, commitment to scrap NEET and restore state medical admissions, Tamil as High Court language, demand for vice-chancellor appointments by state government, opposition to Bharatiya Bhasha Parivar, Governor office reform stance, separate Tamil translation cell. Dense architecture with specific mechanisms and named legislative action.
Demands Tamil recognised as an official Union language, Tamil in the Madras High Court, 25 Tamil Chairs in international universities, continuation of Keeladi and Adichanallur excavations. Two-language policy defence with explicit attribution to Arignar Anna. The classical Tamil plank is strong. The federalism combat posture is lighter than DMK's.
Two-language policy, NEET abolition demand, High Court language reform, Supreme Court bench in Chennai, Governor office abolition, opposition to delimitation, opposition to one-nation-one-election, Cauvery rights defence, Katchatheevu reclaim, Indian citizenship for Eelam Tamil refugees resident in Tamil Nadu. Substantial Dravidian-federal stack. Rs 500 crore for Tamil cultural site restoration. Holds at 4 because the language and identity architecture, while dense, is a recognisable restatement of the DMK-Dravidian position rather than an original one.
The most radical identity position in the set. Tamilar-as-national-identity framing rather than Dravidian. Prabhakaran named as national leader. Tamizham declared by government order, framed in the manifesto as the recovery of a pre-Dravidian Tamil philosophical tradition ("meyyiyal") rather than the founding of a new faith. Tamil as the only language of all courts from Supreme Court downward within the state. 85% reservation for Tamils in both public and private sector employment. Separate state constitution right asserted. Linguistic-nationality federal devolution model. The manifesto does not treat Tamil identity as one position among many; it treats Tamil nationhood as the organising principle of the document.
DMK and NTK both hold 5 but from different starting positions. DMK's Dravidian federalism is institutional and negotiative. NTK's Tamil nationalism is ideological and maximalist. TVK sits between. AIADMK is recognisable within the Dravidian consensus but without the combat posture.
Anti-corruption mechanism, digital service delivery, grievance redressal architecture, transparency provisions, and whistleblower protection.
Dravidian Model 2.0 Super App with 1,000 government services, Single Window system for industrial clearances, DigiLocker integration, self-certification framework, e-governance expansion across departments. The commitment includes named service counts and explicit integration architecture. Anti-corruption posture is rhetorical and relies on inheritance from Periyar-Dravidian tradition rather than a named new body, which is what holds it at 4 rather than 5.
E-Seva strengthening, Single Window for industry, grievance redressal via Manu Neethi Naal and Chief Minister's Special Cell, web portal upgrades for complaint tracking. Named commitments with some mechanism. The manifesto attacks DMK on corruption extensively but does not name a corresponding anti-corruption institutional mechanism of its own. Limits the score to 2.
Vettri Tamil Nadu Super App with 500 government services from mobile phones including birth certificates, ration cards, driving licences. Makkal Arangam citizen grievance platform. Urimai Attai rights cards. 10% of district budgets to be participatory. Lanjam anti-corruption helpline. Tamil Nadu Official Monitoring Platform. Commitment plus mechanism plus distinctive institutional design. Costing and timeline absent.
The most substantive anti-corruption architecture in the set. Dedicated Corruption Eradication Commission with state-level chief commissioner and district-level deputy commissioners holding independent authority. Service Rights Act with defined timelines for every government service. Whistleblower protection law. 100% online transparency for mining permits and government contracts. Annual public reading of local audit reports. Zero tolerance environmental corruption. Most distinctive: mandatory government-hospital-use for all IAS, IPS, IFS, IRS officers, ministers, MPs, and MLAs. This turns accountability into a structural incentive for ministers to upgrade public hospitals they themselves must use. No other manifesto has this.
NTK has the strongest anti-corruption architecture but lightest delivery record. DMK has delivery capability but weaker anti-corruption commitment. TVK sits between with citizen-platform ambition. AIADMK under-commits on what is usually its strongest attack line against DMK.
Water body restoration, flood management for Chennai and other cities, pollution response, climate commitments, and urban planning posture.
47,920 lakes and water bodies restoration commitment, 2 crore tree saplings per year, 20% urban green cover target by 2030, 100 coastal sanctuaries. Specific numbers and timelines. The incumbency adjustment applies because Chennai flooding in the 2023 to 2024 seasons exposed gaps in the urban drainage architecture the 2021 manifesto committed to. The 2026 document does not directly address that gap, which pulls the score from 4 to 3.
Water body restoration named (Seemai Karuvelam removal, check dams, Godavari-Cauvery interlinking advocacy, Cauvery-Vaigai-Gundar completion, Sarabanga lift irrigation). Named commitments without costing or timeline. No urban flood plan, no pollution response framework for Thoothukudi or industrial clusters, no climate commitment.
Cauvery delta environmental restoration with named pollution assessment. Responsible tourism framework with 25% of tourism revenue returning to source districts. Electric auto initiative with tax incentives. Green production push for industrial clusters. Specific to Cauvery delta. Missing: Chennai flood plan, pollution response for industrial clusters, climate commitment.
39,000 water bodies inventoried statewide. Chennai-specific lake restoration naming Long Tank, Vyasarpadi, Kallukuttai, Mogappair, Ayanavaram, Villivakkam, Nungambakkam, Pallikaranai, Velachery. Dedicated green afforestation ministry. Watershed management commitment. Sea-bed research. Environmental corruption zero-tolerance provision. Quarry operation 100% online transparency. Specific commitment plus mechanism. Missing: costing and urban drainage specifics.
TVK, NTK, and DMK cluster at 3 because all three engage water body restoration with specific numbers. None of the four manifestos presents a credible urban drainage plan for Chennai's recurring flood crisis, which is the criterion's biggest gap.
Panchayat-level architecture, named district commitments, municipal reform, and how far each manifesto descends from state-level abstraction.
12,525 village integrated farming programme, 5 lakh self-help groups rural economy framework, Muthalvar Padaippagam expansion beyond Chennai Corporation (co-working spaces with startup incubation, competitive exam coaching, and libraries) to all assembly constituencies, farmer markets in panchayats that do not have them. District-specific naming is thinner than the welfare criterion would suggest.
Kallakurichi and Salem patta regularisation, Karur Inam land handling, Neyveli NLC rehabilitation and resettlement policy, delta district procurement centres, 150-day rural employment, Pandiyar-Punnampuzha river project. District naming is substantive. Local body fiscal devolution is not engaged.
Named district and city commitments: Coimbatore robotics and pump clusters, Tiruppur textile technology centre, Vellore leather cluster, Kanchipuram and Arani weaver cities, Krishnagiri mango direct-to-Chennai supply, Salem and Erode and Coimbatore food tourism corridor, Rameswaram marine tourism district. Rural Olympics, 5 lakh rural houses. District-level naming is the most systematic of the four manifestos in absolute count.
Named Virudhunagar and Thoothukudi and Thenkasi districts for specific agricultural and industrial commitments. Strong sub-district devolution proposal, local government law amendment for autonomy. Ward-level gram sabha, local audit reports at ward level, ward-level sports grounds. Driver licence reform, road infrastructure coordination. Substantive mechanism, limited costing.
All four manifestos speak the language of local governance without committing fiscal architecture to it. TVK has the most district naming by count. NTK has the most devolution-theory content. None produce what the rubric asks for at the 4 or 5 band.
Primary health centre architecture, hospital expansion, disease prevention, women's health, mental health, and the specific mechanisms for delivery.
Makkalai Thedi Maruthuvam doorstep delivery (UN-recognised), Innuyir Kaapom emergency response programme, Muthalvar Marunthagam pharmacy network, dialysis at block hospital level, organ transplant expansion in medical college hospitals, cancer treatment modernisation, integrated mental health centres in all districts, HPV vaccination rolled out in four pilot districts and expanding statewide, palliative and geriatric wards in all medical college hospitals, 24-hour cattle hospitals per district. Delivered architecture plus named expansion.
Reopening of approximately 2,000 Amma Mini Clinics. Amma Master Health Checkup with PET scanning for cancer detection. Rural medical camps for diabetes and blood pressure. Full-cost government coverage for heart and cancer treatment under the insurance scheme. Doctor, dentist, and senior nursing regularisation. Named commitments but little new architecture; most of the package is a restoration posture against the DMK record.
Vettri Nadamaadum Muthiyor Clinic: 1,000 mobile elderly clinics statewide, each staffed with a doctor, nurse, and physiotherapist, reaching every village panchayat with free physical examinations and chronic-disease medication. Thaai Care maternity centres across the state providing accommodation, food, and continuous monitoring for pregnant women near delivery. Garbhini Penngal Udhavi Thogai of Rs 25,000 for pregnant women. Free HPV vaccination for girls aged 9 to 14. Free cervical cancer screening for women over 30. Three new medical colleges in districts without them. Elderly assistance grants of Rs 10,000 for walking sticks, spectacles, wheelchairs, hearing aids. Elderly care homes with qualified staff per district. Substantial commitment with unit-level costing and mechanism.
Tier-architected health system. PHC restructure from one centre per 30,000 population to one per 10,000, with MRI, ECG, and cancer screening at every primary centre, staffed by 2 rotational doctors and 3 nurses. Special hospital within 20 km of every village for cardiac, ENT, dermatology, orthopaedic, and minor surgery. Super-specialty hospitals per district for heart, brain, kidney, liver. Telemedicine integration from every PHC to district hospital. Tamil-medium medical education. Siddha and allopathy parity policy. Dedicated trans hospital in Trichy. Mandatory government hospital use for ministers and senior officials as accountability mechanism. Mechanism-rich, costing absent.
DMK leads on delivered architecture. TVK and NTK both have substantive new commitments but from different directions: TVK focuses on vulnerable-group targeting with unit-level costing, NTK on structural PHC redesign. AIADMK under-commits on health relative to the other three.
School infrastructure, higher education access, teacher welfare, vocational training, and how each party treats the bridge from classroom to employment.
Breakfast scheme covering 19.34 lakh school students. Ullam Uruthi Seyy nutritional programme with 80% of under-six children reached. Puthumai Penn and Tamil Pudhalvan higher education stipends. Sigaram Thodu rural skill training. Muthalvar Padaippagam co-working and competitive exam coaching centres expanding to every assembly constituency. 1,000 model schools. 100% smart classroom target by 2030. Zero Dropout Tamil Nadu goal. UPSC, SSC, RRB preparation centres in knowledge hubs. STEM learning parks. 300 digital libraries. HPV vaccination in girls' higher secondary. Delivered architecture plus named expansion.
Medical school reservation for government school students from 7.5% to 10%. STEM learning centres. Computer science as a sixth subject in grades 6 to 10. Free laptops for government and aided college students. Kalvi TV educational television revival. 10 international-standard universities with Harvard, Oxford, Yale, Cambridge, MIT collaboration. Rural library upgrades to branch libraries. Education loan waiver for certain borrowers. Two-language policy defence. Commitment with mechanism, mechanism lighter than DMK's.
Kamarajar Kalvi Urithithogai of Rs 15,000 per year per student (class 1 to 12) into the mother's account. Kalvi Utharavadham collateral-free education loan of up to Rs 20 lakh from undergraduate through PhD. Vetri Tholirpayirchi internship programme with Rs 10,000 per month for graduates and Rs 8,000 for vocational trainees, targeting 5 lakh beneficiaries annually. 75% Tamil Nadu youth hiring subsidy for private sector (2.5% GST rebate plus 5% electricity subsidy). Teacher Protection Act, regularisation of 5-year-serving temporary teachers, equal-pay-equal-work commitment, foreign training for teachers in Singapore and Finland, AI training for teachers. Thirukkural Valarchi Thittam: cash prizes and education scholarships for students who master 300 kurals, plus global cultural experience and state recognition for students who master all 1,330 kurals. Thirukkural introduced as a special subject in schools and business education institutions. Unit-level costing is present.
Comprehensive new education policy critique with state counter-policy commitment. Tamil-medium education from school through medical college. Primary school curriculum redesign including social justice, ethics, and life skills from class one. Vice-chancellor appointment reform (state government to appoint directly). Research grant transparency mechanism. Tourism university. Siddha medical college. Named commitment but thinner on unit-level mechanism than the other three. Named beneficiary counts, costing, and timelines are absent.
DMK leads because its delivered education record (breakfast scheme, Puthumai Penn, zero-dropout posture) is the strongest in the set. TVK and AIADMK both propose meaningful additions without the delivered-record premium. NTK engages education as ideology more than architecture.
Nine criteria, each scored on a 0 to 5 scale. The scale anchors are fixed:
0 means the manifesto is silent or internally contradictory on the theme. 1 means rhetorical mention without commitment. 2 means named commitment without mechanism. 3 means commitment with mechanism. 4 means commitment with mechanism plus costing or timeline. 5 means commitment with mechanism, costing, and accountability provision.
DMK manifesto in Tamil (488 KB, 3,189 lines of policy content). AIADMK manifesto in English (1,453 lines, 297 numbered items). TVK manifesto in Tamil (96 pages, OCR-processed from the original image-based PDF, with vision reading for pages where OCR quality was insufficient). NTK manifesto in Tamil (converted from a legacy font encoding via CP1252 intermediate decoding plus tam2unicode). Every score is derived from direct reading of these source texts, not from summary or press coverage.
DMK has held office from 2021 to 2026. Its 2026 manifesto continues schemes launched during this term. Where the party's delivered record materially underperforms its 2021 commitments, the corresponding 2026 criterion is adjusted downward by one point. This adjustment is explicit in the fiscal criterion (revenue deficit persists despite 2021 fiscal commitments) and the environment criterion (Chennai flooding in 2023 and 2024 exposed gaps in urban drainage commitments from 2021). No corresponding adjustment applies to AIADMK, TVK, or NTK because they are not the current incumbent.
The similarity analysis is based on sub-theme cluster comparison rather than raw text matching. For each of the nine criteria, the sub-policies each party commits to are identified from the source texts. Pairwise overlap is observed where two parties commit to the same sub-policy with the same direction and mechanism. Differentiation is the inverse of average overlap. This is a qualitative assessment informed by reading the full texts, not a quantitative similarity score, because precise numerical similarity would require a full sub-policy inventory that the publication window did not accommodate.
It cannot predict implementation. A 5 on welfare means the document is rigorous; it does not mean delivery will follow. It cannot measure electoral appeal, cadre strength, or voter turnout effects. It cannot substitute for reading the manifestos themselves, which remains the most honest exercise any citizen can undertake.
This document scores manifestos, not parties. A party's manifesto is one input into its candidacy. The governance record, the candidate quality, the alliance arithmetic, and the voter's own priorities are others. A vote is a compound judgement; this scorecard is one component of that judgement.
The rubric used here is locked and published. If any reader disagrees with how a criterion was defined or weighted, the same method can be applied with different weights to generate a different set of scores. The evidence base is the manifesto text itself, and the text is what it is.
The similarity analysis tells a structural story about Tamil Nadu's political moment. Three of the four manifestos converge on a Dravidian-welfarist baseline that has become the shared political infrastructure of this election. One manifesto stands outside that baseline on ideological grounds. The originality of a manifesto is not the same as the rigour of a manifesto, and this scorecard distinguishes between the two.
A reader who wants to disagree with any score is invited to read the relevant section of the manifesto and apply the rubric directly. The rubric is designed to be reproducible. That is the point.
