However, Purnia registered the sharpest increase (21.14%) among the 32 Muslim-dominated seats in Bihar.
What happened in 2020?
The Tejaswi Yadav-led RJD is known for its proximity to the Muslim community, which has supported it in almost all elections.
Of the 51 Assembly seats in the state’s Muslim-dominated regions, the BJP and its allies won 35 seats in 2020. The NDA’s strike rate was nearly 70 per cent.
Meanwhile in 2015, the RJD, JD(U) and Congress came together under the Mahagathbandhan banner, drawing nearly 80% of Muslim votes.
Exit polls on Tuesday predicted a clear victory for the NDA and a poor showing for the opposition Mahagathbandhan. They also played down Prashant Kishor’s Jan Suraaj party, projecting it to secure only a handful of seats. According to the combined “poll of polls,” the NDA is poised to return to power comfortably with around 148 seats, while the RJD-led Mahagathbandhan, with around 88 seats, is expected to lag significantly behind.
