Tamil Nadu's most one-sided and most divided booths, 2026

• One booth is one row of Form 20 (polling station), including auxiliary stations such as 95A. Only EVM votes count; postal votes are not in booth sheets. A party led a booth when it had the most votes there.
• Share = the leading party's votes divided by all votes at the booth (all candidates and NOTA).
• Ranked: booths with at least 300 valid votes and a row that adds up, in the 218 seats where our booth sheet matches ECI's EVM totals exactly.
• Left out: the other 16 seats whose booth sheet does not match ECI's EVM totals exactly (15 differ by at most 41 votes on any candidate or NOTA; Chengalpattu's published sheet has 4 polling stations with no votes printed and is 2,313 EVM votes short), and Udhagamandalam booth 7, where the sheet records 595 NOTA votes among 768 votes.
• A tie for the lead is not a lead: tied booths are not ranked. Most divided = the gap between the first and third candidate's votes; each Independent counts alone.
• TVK here is Tamilaga Vettri Kazhagam; ECI prints the code TVK for a second party too, Tamizhaga Vaazhvurimai Katchi (TVAK).
• Place names are village, ward or area names as on the booth pages.
• A booth is a few hundred voters; where a party leads by a wide margin in a booth, this says nothing about why, or about any individual voter.

Among booths with at least 300 valid votes, booth 93 in Marupalli (Thalli seat), where CPI took 642 of 673 votes, 95.4%. The best DMK booth was booth 72 in Melvisharam (Ranipet seat): 820 of 876 votes, 93.6%.

Booth 70 in Thottiampatti (Rasipuram seat): BJP 293, TVK 293 and DMK 292 of 920 votes, one vote between the first and the third candidate.

A booth with a few dozen votes can show almost any share, so a ranking of tiny booths means little. With a floor of 300 valid votes, every share rests on at least a few hundred votes.

From Form 20 (polling-station-wise results) published by the Chief Electoral Officer, Tamil Nadu, checked against the results the Election Commission of India declared for all 234 seats. Seats where the two do not match exactly are left out.
