West Bengal, the biggest and most politically crucial state going to the poll, will be a thrilling cliffhanger but the opinion polls differ on who will seize the crown. The India Today-Axis My India poll forecasts that Chief Minister Mamata Banerjee might fall short on the numbers to form a government, but the ABP-C Voter poll gives her a clear win. Republic TV-CNX reckons the BJP will squeak past the winning post. In Assam, Kerala and Tamil Nadu the poll predictions are more along expected lines with the polls handing Assam to the BJP and the LDF winning over the UDF in Kerala. In Tamil Nadu, the DMK is expected to take power after decimating the ruling AIADMK, the polls say. The ABP-C Voter poll predicts the Congress will make big gains in Assam even though it is likely to fall short of the numbers.
