About the Party
Nitish Kumar's JDU dominates Bihar politics and is a crucial NDA ally. Kumar has pivoted between NDA and INDIA alliance multiple times, earning the nickname 'Paltu Kumar'. JDU won 85 seats in the NDA's 202-seat sweep of the 2025 Bihar elections — its best showing since 2010 — before Nitish moved to the Rajya Sabha in April 2026, handing the CM chair to BJP's Samrat Choudhary.
