The Cauvery delta, often referred to as the agrarian heartland of Tamil Nadu, is poised to play a significant role in the upcoming elections. Historically, the party securing the majority of seats in this region has been able to form the state government. In the 2021 elections, the Dravida Munnetra Kazhagam (DMK) party achieved a remarkable victory, winning 37 out of 41 constituencies across nine districts. As the elections approach, the DMK is focused on retaining its power. Meanwhile, the All India Anna Dravida Munnetra Kazhagam (AIADMK) is looking to recover from its previous losses, which were exacerbated by vote splits from the Amma Makkal Munnetra Kazhagam (AMMK) and the Naam Tamilar Katchi (NTK). The AIADMK is optimistic that anti-incumbency sentiments will favor them this time. They have formed alliances with the AMMK and the Tamil Maanila Congress (Moopanar) to strengthen their position in the delta. However, the influence of the AMMK may be constrained due to internal divisions, particularly regarding V. K. Sasikala and her political maneuvers, which could impact the party's ability to secure the Kallar vote bank. The dynamics in this region will be critical as the elections draw nearer.
