The 2026 West Bengal assembly elections are set to redefine the state's political map, moving beyond established strongholds to a broader contest for survival. Traditionally dominated by the Trinamool Congress (TMC), regions like Diamond Harbour in South 24 Parganas are under intense scrutiny, with the Election Commission deploying anti-terror units to ensure transparency amid concerns over electoral integrity. The TMC's historical reliance on significant victory margins may be tested as the opposition, particularly the Bharatiya Janata Party (BJP), strengthens its position in the northern districts, focusing on tribal development and labor reforms. Meanwhile, the western districts of Jangalmahal have emerged as critical swing zones, where economic revitalization has become a focal campaign issue. The outcome in 21 marginal seats, particularly in the urban fringes of Kolkata and industrial towns like Hooghly and Howrah, will be pivotal, with victory margins projected to be less than two percent. With a statewide turnout of 93.19 percent, these contests could lead to a significant shift in the assembly's balance of power, with the official results expected on May 4.
