West Bengal's Post-SIR Rolls Redraw Voter Profiles Ahead of 2026 Assembly Polls

West Bengal's post-SIR rolls have reduced the electorate by 8.3% and redrawn the state's demographic and political geometry ahead of the 2026 assembly polls. Voter churn is significant, particularly in border districts, refugee-dominated pockets, minority-heavy belts, and urban constituencies. The exercise introduces structural variables, including demographic filtering in border belts, stress on social coalitions in Matua and minority districts, and recalibration in urban and Junglemahal regions. The TMC and BJP contest these areas, with the TMC traditionally delivering substantial leads in minority-heavy belts.
