Didi can't make up her mind who to side with. She thinks it would be congress, because they do much better than BJP in WB, but can't be sure - if the government falls and the vote is in six months, she may not want to go with Congress. The problem with Mamta is that she is an opportunist and therefore, unable to lead. Most of her South Calcutta voters would want her to go and vote for the government, but she is not sure which boat to jump on. It is sad that such people survive in politics because the rest of the system is also as bad and unprincipled.
