What would it take to win?

In April the AIADMK won this seat. Its MLA, K. Maragatham Kumaravel, joined TVK on 25 May 2026 and is TVK’s candidate in the by-election of 6 October 2026. So the question is simple: will April’s AIADMK voters stay, follow the former MLA to TVK, or switch to DMK?

April 2026 votes
TVK61,738
DMK59,048
AIADMK68,544 · won

TVK If about 1 in 20 AIADMK voters go with the former MLA to TVK, TVK wins.

That is 3,404 people.

1 of every 20 AIADMK voters

DMK If about 1 in 14 AIADMK voters switch to DMK, DMK wins.

That is 4,749 people.

1 of every 14 AIADMK voters

AIADMK If fewer than that leave, AIADMK wins.

It can lose up to 3,402 voters to TVK, or 4,747 to DMK, and still come first.
