In West Bengal, the 2026 Assembly elections are shaping up to be highly competitive, particularly in 57 constituencies where the margins of victory were under 8,000 votes during the 2021 elections. The Trinamool Congress (TMC) won 29 seats while the Bharatiya Janata Party (BJP) secured 28, indicating a closely matched contest. Notable battlegrounds include Nandigram, where Leader of Opposition Suvendu Adhikari defeated Chief Minister Mamata Banerjee by just 1,956 votes, and Dinhata in Cooch Behar district, where BJP leader Nisith Pramanik won by a mere 57 votes. However, a subsequent bypoll saw the TMC reclaim the seat by over 1.6 lakh votes, illustrating the volatility of these constituencies. The report highlights that 19 of these seats were decided by fewer than 3,000 votes, making them particularly sensitive to local shifts. The majority of these critical constituencies are located in south Bengal, with a significant concentration in the western belt, including districts like Purba Medinipur and Bankura. The upcoming elections will also be influenced by economic issues and identity politics, especially in border districts like Nadia and North 24 Parganas. With a potentially fragmented political landscape, minor shifts in voter sentiment could have outsized impacts on the electoral outcomes.
