Bihar Chief Minister Nitish Kumar must be repenting his decision of snapping ties with the NDA, in whose Government he had served as a Union Minister, over the issue of Mr Narendra Modi. All opinion surveys have been predicting the surge of the BJP with Mr Modi as the prime ministerial candidate, and the decimation of Mr Nitish Kumar’s party in Bihar.
