In the lead-up to the 2026 West Bengal Assembly elections, approximately 57 constituencies have been identified as critical battlegrounds, where the margins of victory in the 2021 elections were under 8,000 votes. The Bharatiya Janata Party (BJP), which secured 77 seats in 2021, holds 23 seats that were won by narrow margins, with the tightest being in Dinhata, where Nisith Pramanik won by just 57 votes. The Trinamool Congress (TMC), which achieved a landslide victory in 2021, has 34 seats won by slim margins, highlighting potential vulnerabilities ahead of the next election. The unpredictability of these contests is further exacerbated by the Special Intensive Revision (SIR) that removed over 9.1 million voters, with deletions in many of these seats exceeding the original victory margins. This situation makes the upcoming election highly competitive and uncertain, as both parties will focus intensely on these pivotal constituencies.
