Tamil Nadu witnessed a remarkable voter turnout of 84.98% in the Assembly elections held on April 23, 2026, marking its highest since Independence. As anticipation builds for the exit polls, set to be released on April 29, the historical accuracy of these polls reveals a pattern of mixed results. In previous elections, such as in 2021, exit polls accurately forecasted the Dravida Munnetra Kazhagam (DMK) alliance's victory but inflated the predicted seat count, estimating between 175 and 195 seats while the DMK secured only 159 seats. Similarly, in 2016, most polls incorrectly predicted a DMK-led win despite the AIADMK's actual success with 136 seats. Current opinion polls indicate a competitive race, with the DMK alliance projected to win 113 to 123 seats, while the AIADMK-led National Democratic Alliance (NDA) is estimated to secure 107-120 seats. As the election results approach, the accuracy of these predictions will be closely scrutinized.
