Prashant Kishor's impressive Bankipur by-election victory significantly disrupts Bihar politics. His focus on issues like education and corruption, rather than caste arithmetic, challenges the status quo. Winning in a BJP bastion, this signals a warning against BJP complacency and voter reluctance towards the RJD, suggesting a search for new political alternatives. Kishor enters the assembly amidst Bihar's political churn, with Nitish Kumar moving and RJD appearing diminished. He now has a crucial platform to shape the state's future at a fraught moment.
