Evidence-Backed Comparison

DMK vs AIADMK — election performance comparison

Sources: ECI, affidavits, published records Method is public and auditable

Direct answer High confidence

DMK and AIADMK are the two dominant parties in Tamil Nadu elections. A meaningful comparison requires looking at win rates, vote share, criminal case averages, and declared assets together — not just seat counts — because alliance seat-sharing can inflate or deflate raw numbers.

Where Greatidude adds evidence beyond seat counts

  1. Criminal cases per party: Candidates page shows IPC-section criminal case counts from ECI affidavits for every 2026 candidate.
  2. Asset declarations: Average declared assets per party from affidavit Schedule data — cross-linked to the original ECI filing.
  3. Promise fulfilment: For elected MLAs, the Promise Tracker tracks kept, broken, and pending promises against public records.
  4. Gap scores for incumbents: The Leaderboard shows which sitting MLAs have the largest gap between perception and documented reality.

Why raw seat count comparisons mislead

Alliance seat-sharing means a party's "win count" is not comparable across elections without controlling for seats contested. A party that contests fewer seats as part of a larger alliance can show a higher win rate while its total vote share is lower. Always cross-check seats contested, vote share, and affidavit quality together.

Consistent party-comparison protocol

Protocol version: party-compare-v1

  1. Fix election scope and candidate universe before comparing parties.
  2. Use the same metric definitions and formulas for both parties.
  3. Separate raw scale metrics (tickets, votes, seats) from conversion metrics (win rate, near misses).
  4. Publish data-readiness status for community, age, and gender segmentation before drawing fairness conclusions.
  5. Attach methodology, transparency, and uncertainty notes in every comparison page.
Standard metric Formula Interpretation
Tickets fielded Count of candidates fielded by party in election scope Opportunity surface and coalition strategy footprint
Seats won Count of candidates with outcome = WON Raw outcome power
Win conversion % (seats won / tickets fielded) x 100 Conversion efficiency independent of raw ticket volume
Two-party vote share % (party total votes / sum of two compared parties total votes) x 100 Relative voter pull within the compared pair
Near-miss pressure Count of rank-2 losses (plus subset under 5,000 margin) Expandable frontier for next-cycle conversion
Winner margin profile Average and median winning margin Victory depth and stability
Integrity and candidate profile mix Avg criminal cases, zero-criminal share, assets, education, incumbent %, turncoat % Candidate quality and risk distribution
Demography readiness Availability of community/age/gender fields in payloads Determines whether social-justice segmentation can be measured directly
