To analyse this question a bit impartially, first you have to ask whether INC has held itself together. 1/n
1. In 1998, Mamata Banerjee, a congress leader, split from the party and made Trinamul Congress. She governs West Bengal now. Marginal presence of INC in the state now.
NCP is a major political party on its own right in Maharashtra now.
He governs Andhra Pradesh today and INC has marginal presence in the state.
The reasons for his rift, he has made amply clear multiple times.
From the largest party in the state as per people's mandate to almost a nothing in the state.
Thus making a BJP Government in the state.
It is up to the concerned party to decide who should be its leader and who should be not. It is their business.
But when a statement becomes a sentiment, its accuracy is certainly something to be commented on.
