Vijay won the floor test with 144 ayes — 26 above the 118 majority mark. The DMK + DMDK walkout (60 MLAs) dramatically inflated the margin. Here is exactly how every vote broke.
TVK's voting strength was 105 (not 108) — the Speaker cannot vote, and Vijay had vacated Trichy East. The 25 AIADMK rebels pushed the count far above what allies alone could deliver. CPI, CPI(M), VCK and IUML extended support while continuing SPA membership.
SP Velumani led 25 AIADMK MLAs who defied EPS's official whip. EPS threatened anti-defection action under the 10th Schedule. Udhayanidhi Stalin called the crossovers "not change but exchange." DMDK's Premalatha spoke against horse-trading but her only MLA joined the DMK walkout.
Every mandate is best understood against the last. Here is exactly what shifted, party by party, over five years.
Net seat change per party. Green = gained. Red = lost. TVK is a debut baseline — no 2021 comparison possible.
| Party | 2021 | 2026 | Net Change | Visual Swing | What drove it |
|---|---|---|---|---|---|
TVK | — | 108 | ★ Debut | Anti-incumbency; Vijay's fan-club mobilisation turned party; first-time voters, youth, urban, women voters; digital-first campaign; swept 20 of 22 Chennai seats | |
DMK | 133 | 59 | ▼ 74 | Governance fatigue; Stalin lost Kolathur (2nd sitting TN CM to lose own seat after Jayalalithaa in 1996); TVK ate youth/urban vote; complete rout in Kancheepuram, Thiruvallur, Chengalpattu, Vellore | |
AIADMK | 66 | 47 | ▼ 19 | BJP reunion (Apr 2025) alienated urban AIADMK voters; TVK made inroads into Kongu and western TN strongholds; party then split on floor of house with 25 rebels | |
INC | 18 | 5 | ▼ 13 | TVK ate INC's urban and minority vote base; still pivoted as kingmaker post-result by leaving SPA to back TVK | |
VCK | 4 | 2 | ▼ 2 | TVK won 24 of 46 SC reserved seats — breaking VCK and DMK's Dalit vote base; VCK still gave outside support to TVK | |
PMK | 5 | 4 | ▼ 1 | Party split (Anbumani vs S. Ramadoss factions) diluted Vanniyar consolidation in north TN | |
BJP | 4 | 1 | ▼ 3 | AIADMK re-alliance backfired; lost all 2024 momentum; Annamalai sidelined in AIADMK alliance; near-total wipeout | |
CPI(M) | 2 | 2 | → 0 | — | Held both seats; remained SPA members but gave unconditional outside support to TVK to prevent BJP back-door government |
CPI | 2 | 2 | → 0 | — | Held both seats; remained SPA members; gave outside support to TVK citing BJP's back-door government attempt |
NTK | 0 | 0 | → 0 | — | Contested all 234 seats; held ~4% vote share — down from 6.58% in 2021, geographically dispersed. FPTP system yields 0 seats. Seeman's base intact; actual vote share pending ECI Form-20 |
AMMK | — | 1 | — | — | TTV Dhinakaran in AIADMK alliance; won 1 seat (Kamaraj); Kamaraj then voted for Vijay in floor test and was immediately expelled from AMMK |
