Not only Mamata, but Calutta and its greater areas are stronghold of TMC, Congress.
In last election CPM won, NOT because Bengali Middle class deserted Mamata. But because Muslims were manipulated by CPIM's communal propaganda. IT WAS OPENLY WRITTEN BY ANANDABAZR, PRATIDIN IMMEDIATELY AFTER ELECTION.
Calcutta is bastion of middle class, rightwing politics. Not only in WB, but also in India. Its the place where great anti-partition of bengal movement was faught.
Shyama Prasad Mukherjee etc ruled Calcutta for a long time.
Once Congress delines permanently, Calcutta will become a Saffron Stronghold.
