Karaikudi in Tamil Nadu faces a four-way contest on April 23. Congress's Karti Chidambaram, NTK's Seeman, TVK's Dr T K Prabhu, and AMMK's T T V Dhinakaran compete. Seeman's rising vote share from 1.06% in 2016 to 6.89% in 2021 poses risks. Actor Vijay's TVK entry adds uncertainty. Congress aims to retain the Chettiars' heartland constituency amid shifting political dynamics.
