The 2021 Assembly elections across five Indian states—West Bengal, Tamil Nadu, Kerala, Assam, and Puducherry—highlighted the mixed accuracy of exit polls. In West Bengal, most polls suggested a close contest between the Trinamool Congress (TMC) and the Bharatiya Janata Party (BJP), with projections indicating the BJP could secure over 100 seats. However, the TMC won decisively with 215 seats to BJP's 77 in the 294-member Assembly. Conversely, Tamil Nadu's exit polls were more aligned, predicting the DMK-led alliance would secure over 160 seats, which they did, winning 159. Kerala's exit polls anticipated a break from a four-decade tradition of alternating governments, with the Left Democratic Front (LDF) winning 99 seats in the 140-member Assembly. In Assam, exit polls indicated the BJP-led alliance would retain power, which they did, winning 75 seats. Finally, in Puducherry, exit polls suggested a government change, with the NDA forming the government with 16 seats. Overall, while exit polls can indicate likely winners, their accuracy in seat projections varies significantly, especially in closely contested elections.
