The upcoming 2026 assembly election in West Bengal is set to be influenced significantly by a recent Special Intensive Revision (SIR) of electoral rolls, which has led to the deletion of over 90.83 lakh names, accounting for nearly 11.85% of the electorate. This revision has particularly affected around 65-70 constituencies, where previous election outcomes were decided by very slim margins, often less than 8,000 votes. Key constituencies like Nandigram and Bhabanipur, along with regions in North 24 Parganas and Murshidabad, are now battlegrounds for both the ruling Trinamool Congress (TMC) and the opposition Bharatiya Janata Party (BJP). In the 2021 elections, the TMC won 29 of the 57 seats decided by margins of 8,000 votes or less, while the BJP secured 28. The current deletions could drastically alter these dynamics, as many areas have seen voter roll reductions exceeding previous victory margins. Both parties are now strategizing to address the impact of these deletions, with the TMC aiming to maintain its foothold and the BJP seeking to capitalize on the changes. The political landscape is thus poised for a contentious battle as both parties prepare for the elections.
