By-elections for a single seat, especially an Assembly seat, are usually low-key affairs. However, the by-election for the high-profile Bankipur seat in Bihar's capital Patna has grabbed eyeballs thanks to the entry of Prashant Kishor, former election strategist and founder of Jan Suraaj Party.
The Bankipur seat has been a Bharatiya Janata Party (BJP) stronghold since 1995. The party has consistently won the seat—and often by significant margins. Initially, BJP leader Nabin Kishore Prasad Sinha, BJP President Nitin Nabin's father, won four consecutive elections.
Following his death in 2006, his son Nitin contested the by-election and entered the Bihar Legislative Assembly for the first time. At that time, the constituency was called Patna West. In 2008, following delimitation, the Patna West seat ceased to exist, and the new Bankipur Assembly constituency came into existence.
