Alliance lens

IUML is part of SPA — Secular Progressive Alliance

State-level reflection of the INC-led UPA / INDIA-bloc coalition. Congress is a member; DMK leads at state level. Members: DMK, INC, VCK, CPI, CPI(M), IUML, MDMK, DMDK.

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.

Numbers from Form 20, narration from this site’s editorial layer. Every number in this page traces back to a row in the per-AC drilldown JSON.
