Hasanpur is often cited among key battlegrounds as it lies in a region with mixed caste and minority presence; whoever wins here indicates alliance strength. Back then with RJD, Lalu Yadav’s son Tej Pratap Yadav is the incumbent from the seat. He won the last polls with 80,991 votes in his favour, defeating JD(U)’s Raj Kumar Ray who garnered 59,852 votes.
