Booth share spectrum
46,160 contested boothsHow every booth this party contested distributes by share — from wipeout (red) to fortress (green). Most booths sit in the strong band (30–50%) — 47% of contested booths.
Fortressesbooths above 80% share
351DMK crossed 80% share in 351 polling stations — more than any other party. The top fortresses concentrate in three patterns: minority Muslim areas where IUML stood aside (Kayalpattinam, Melvisharam), SC-reserved seats where the DMK candidate ran unopposed by an alliance partner (Vasudevanallur), and dense urban DMK wards in Ranipet and Tiruchendur.
Hot pocketsbooth share far above AC average
736These are booths where DMK's vote share at the polling station was at least 35 percentage points above its average across that constituency. The biggest pockets cluster in Manapparai and Vasudevanallur, where micro-localities delivered 80-90% even though the seat itself was competitive.
Knife-edgesbooths decided by 2 votes or fewer
583DMK won 301 polling stations by 2 votes or fewer — 50 of them by a single vote. Thiruvallur (AC 4) alone produced 23 knife-edge wins.

Methodology & Sources
Source data: ECI Form 20 (statutory booth-level result statements) for all 234 Tamil Nadu Assembly Constituencies, 2026. Per-AC files committed at data/ac-drilldown/.
Booth-size threshold: only polling stations with at least 200 valid votes are included in any list. This excludes micro-booths (typically auxiliary stations with <100 voters) where a 100% share is statistically trivial.
Extremes-only framing: averages, by-district rollups, and median statistics are deliberately omitted. Each list is gated by a hard threshold — fortresses (≥80% share), wipeouts (<1% share), hot/cold pockets (booth share ±35 percentage points from AC average), knife-edges (margin ≤2 votes).
Alliance composition: TN 2026 alliances are hand-curated in data/ac-insights/context/alliances.json. SPA (DMK + INC + VCK + CPI + CPI(M) + IUML + MDMK + DMDK) reflects the INC-led UPA / INDIA bloc at state level. NTDA (AIADMK + PMK + BJP + AMMK) reflects the BJP-led NDA. TVK and NTK contested alone, outside both national blocs.
Demographic tags: only two are used — minority_muslim_area and minority_christian_area — applied to a small hand-curated list of widely-known localities (10 Muslim-area locality keywords; 4 ACs in the Kanyakumari Christian belt). Tags describe locality context, not voter intent. Caste demographics, population numbers, and Census citations are deliberately not used; readers can infer further context from booth names, AC names, and district names. SC-reserved seats are already labelled in the AC name itself.
