CPIM is in dire straits. They know that after what has happened in Nandigram its very difficult to win election in WB without their usual tactics. Also they can't afford that people say that Buddhadev is a bigger killer than Modi. After all Modi doesn't shy away from hindutva. But before Nandigram nobody would have believed of anti-muslim stance of commies. So in order to show that their hands are cleaner than Modi, they are creating so much of hullaboo.
