In Bihar’s safest seat, Bankipur, the BJP’s vote share fell from a historic 59% to just 34%, while Prashant Kishor’s Jan Suraaj Party surged past 48%. The shift could reshape both state politics and the BJP’s national caste calculus.

Key Takeaways

  • BJP lost its long‑standing dominance in Bankipur.
  • Prashant Kishor’s Jan Suraaj Party is now polling close to 48%.
  • Discontent among upper‑caste voters may threaten the party’s broader coalition.

Bankipur, a Patna‑based assembly seat that the BJP has never lost since its creation in 2008, is now leaning heavily towards Prashant Kishor after 25 counting rounds, with a lead of roughly 15,000 votes. The BJP’s vote share has slipped to 34%, a stark drop from the 62% it secured in the 2025 state elections.

Caste‑wise estimates show that upper‑caste groups make up about 37% of the electorate (excluding Banias, who are OBC in Bihar). The last‑minute replacement of the BJP candidate, combined with dissatisfaction over the party’s decision to name Kushwaha chief minister, has alienated many traditional supporters.

This erosion of upper‑caste support is especially worrying because the BJP previously relied on a delicate balance between upper castes, OBCs, and EBCs under Nitish Kumar’s glue‑politics. With Nitish out of the picture, the party risks losing its OBC‑EBC base if it tries to appease upper‑caste demands.

Historical Background

Since its delimitation in 2008, Bankipur has consistently delivered over 59% of votes to the BJP. In the 2025 state polls, the party swept Bihar, winning 202 out of 243 seats, yet this stronghold now shows a dramatic swing, highlighting cracks in the BJP’s caste‑based formula.

Why This Matters

BozokMedia analysis shows that the erosion of upper‑caste support in a traditionally BJP stronghold could foreshadow a broader shift ahead of the 2029 Lok Sabha polls, forcing the party to recalibrate its caste‑coalition strategy.

"The Bankipur setback is less a one‑off by‑poll loss and more a symptom of a weakening upper‑caste alliance," notes political analyst Dr. Ajay Singh.
