In the upcoming elections, Deputy Chief Minister Udhayanidhi Stalin is vying for re-election from the Chepauk-Thiruvallikeni constituency in Chennai, Tamil Nadu, a seat historically held by the Dravida Munnetra Kazhagam (DMK). Stalin, who won by over 60,000 votes in his debut election in 2021, returns with a strengthened position as Deputy Chief Minister. The DMK highlights achievements in infrastructure, including improved drainage, upgraded health facilities, and new schools. Party representatives anticipate an increased victory margin, projecting over one lakh votes this time.

However, the opposition, led by AIADMK candidate Adhi Rajaram, is intensifying its campaign, questioning the DMK's governance and alleging failures in basic amenities and safety. Concerns about dynastic politics are also raised against Stalin, who comes from a prominent political family. The electoral landscape has further shifted with the entry of the Tamil Maanila Congress (TVK), which is banking on the popularity of actor-turned-politician Vijay, introducing a new dynamic to the contest. Voter opinions in Chepauk are divided, with some praising Stalin's contributions while others express concerns about safety and basic needs. As campaigning heats up, the outcome in Chepauk-Thiruvallikeni could reflect broader trends in Tamil Nadu's political landscape.
