Prashant Kishor’s victory in the Bankipur by-election is not merely a first electoral success. In Bihar’s political language, it is the capture of a fortress. Prashant Kishor won by 19,324. Prashant Kishor claimed JD(U) is facing an existential crisis and will rapidly disintegrate into rival factions once Chief Minister Nitish Kumar steps. Ahead of the bypoll, Kishor said he had deliberately chosen not to contest from a politically safe constituency.
