Tamil Nadu Elections: High Voter Turnout and Key Constituency Battles

With voting concluded across all 234 constituencies in a single phase on April 23, Tamil Nadu has recorded one of its highest-ever voter turnouts, crossing 84.80 per cent. The counting of votes is scheduled for May 4, when the fate of the state will be decided. The election has evolved into a high-stakes, multi-cornered contest. The ruling Dravida Munnetra Kazhagam (DMK), led by chief minister MK Stalin, is seeking continuity based on its governance and welfare record. The opposition All India Anna Dravida Munnetra Kazhagam (AIADMK), led by Edappadi K Palaniswami is attempting a political comeback, while Vijay's Tamilaga Vettri Kazhagam (TVK) has emerged as a disruptive force, particularly among urban and youth voters.

Kolathur remains one of the most politically significant constituencies in the state. Stalin is contesting here for a fourth consecutive term, having held the seat since 2011 and winning comfortably in both 2016 and 2021 with over 60 per cent vote share. He faces AIADMK's P Santhana Krishnan, while TVK has fielded VS Babu. In the 2021 assembly elections, Stalin secured 1,05,522 votes (60.9% vote share), defeating AIADMK's Aadirajaram, who polled 35,138 votes, by a wide margin. The constituency, located in Chennai, has evolved into a dense residential-commercial area with rising pressure on civic amenities. Voter turnout in this high-profile seat surged to 86.12 per cent, compared to 61.68 per cent in 2021, reflecting heightened political engagement.

Perambur has emerged as a key battleground with Vijay making his electoral debut. He faces sitting MLA RD Shekar of the DMK, while the AIADMK-led alliance has fielded M Thilagabama and NTK has nominated S Merlin Siriya Pushpam. In the 2021 elections, Shekar won with 1,05,267 votes (52.5% vote share), defeating AIADMK’s NR Dhanapalan, who secured 50,291 votes. A working-class constituency in North Chennai, Perambur’s politics is shaped by labour issues and civic concerns. The voter turnout rose sharply to 89.74 per cent from 63 per cent in 2021, making it one of the most closely watched seats.

Tiruchirappalli (East), a fully urban constituency, has become a key contest with Vijay in the fray against AIADMK’s G Rajasekaran. In the 2021 assembly elections, DMK’s S. Inigo Irudayaraj won with 94,302 votes (54.56% vote share), defeating AIADMK’s N. Vellamandi Natarajan by a margin of 53,797 votes. The constituency has historically alternated between the DMK and AIADMK, with the DMK securing a decisive win in the last election. Vijay’s presence has introduced a new variable, particularly among urban and younger voters.

Bodinayakanur in Theni district is the home turf of former chief minister O Panneerselvam, who is now contesting on a DMK ticket. He faces AIADMK’s VT Narayanasamy. In the 2021 elections, Panneerselvam won with 1,00,050 votes, defeating DMK’s Thanga Tamil Selvan by 11,021 votes. Historically dominated by the AIADMK, the seat has seen the party win seven times since 1977, while the DMK has won twice, making this a crucial test of shifting loyalties.

Edappadi, located in Salem district, is a key contest featuring AIADMK chief Edappadi K Palaniswami, who is seeking to retain his stronghold. He faces DMK’s Kasi C. In the 2016 assembly elections, Palaniswami won with 98,703 votes, defeating PMK’s Annadurai N by 42,022 votes.

Mylapore is witnessing a triangular contest between DMK’s Dha Velu, BJP’s Tamilisai Soundararajan and TVK’s P Venkataramanan. Soundararajan is the former Governor of Telangana. In the 2021 elections, Velu won with 68,392 votes (44.95% vote share), defeating AIADMK’s R. Nataraj, who secured 55,759 votes. The constituency recorded a voter turnout of 74.89 per cent this year, up from 56.24 per cent in 2021.

Chepauk–Thiruvallikeni is a key constituency featuring deputy chief minister Udhayanidhi Stalin of the DMK against AIADMK’s Aadirajaram, with TVK’s D Selvam also in the fray. In the 2021 elections, Udhayanidhi Stalin won with 93,285 votes (67.9% vote share), defeating PMK’s Kassali AVA, who contested as part of the AIADMK alliance. The voter turnout rose to 84.28 per cent from 57.82 per cent in 2021.

Sriperumbudur is witnessing a three-way contest between Tamil Nadu Congress Committee president K Selvaperunthagai, AIADMK’s K Palani and TVK’s K Thennarasu. In the 2021 elections, Selvaperunthagai won with 1,15,353 votes (43.65% vote share), defeating Palani by 10,879 votes. The voter turnout rose to 86.09 per cent this year from 74 per cent in 2021.

Sattur, located in Virudhunagar district, is witnessing a contest between BJP state president Nainar Nagendran and Ajith M from TVK. In the 2021 elections, ARR Raghuraman of the MDMK (contesting on a DMK symbol) won with 74,174 votes, defeating AIADMK’s RK Ravichandhran by 11,179 votes.

The 2026 election is not just about forming the next government but about the future of Tamil Nadu’s political structure. For Stalin and the DMK, it is about continuity, consolidation, and potentially achieving consecutive terms. For the AIADMK, it is about revival after internal challenges following the post-Jayalalithaa phase. For Vijay’s TVK, it is a first major test of whether celebrity-driven mobilisation can translate into electoral success.
