Sitting MP Ashwini Kumar Choubey is contesting the seat again and she is facing RJD's Jagdanand Singh. BSP has fielded a candidate, Sushil Kushwaha, on the seat. In 2014, BSP had garnered 20.8 per cent vote share in Buxar and 2019 could thus become a triangular contest. Former MLA and RJD leader Ram Chandra Yadav is also in the fray as an independent. The rebel leader could cut into RJD's vote share and end up helping BJP.
