AIADMK Faces High-Stakes Dharapuram By-Election Challenge
Dharapuram is holding a special election because its former AIADMK lawmaker, Sathyabama, resigned.
She is now running for the TVK party.
The AIADMK has won this seat many times in the past.
But TVK became a major party in the 2026 state election, changing the contest.
Analysts say younger voters and government welfare programs could help TVK.
The AIADMK wants to keep its supporters from leaving.
The DMK is also trying to stay competitive despite problems in its alliance.
The CPI is running a candidate too.
The result could show how much support each party has now.
The Dharapuram by-election was triggered by AIADMK MLA Sathyabama’s resignation; she is now contesting on the TVK ticket.
The AIADMK has won Dharapuram six times since the Emergency, while its ally PMK won once.
In the April 2026 assembly polls, AIADMK received 40.56% of votes, DMK 32.20%, and TVK 23.23%.
Analysts say TVK leader and Chief Minister C. Joseph Vijay may attract younger voters, while government welfare schemes could help the party.
The DMK is also seeking to remain competitive amid alliance strains, while the CPI is contesting to demonstrate its strength.
