The 2020 Bihar Assembly election was the closest contest in the State's history in many ways. In this election, in 20% of the seats, the margin of victory was less than 2.5% of the votes polled, the highest share of such seats in the last 14 elections.

However, such wafer-thin margins may not have influenced the final tally much in the 2020 polls, as both the alliances won tightly contested seats in nearly equal numbers. The BJP and JD(U) won 21 seats with a less than 2.5% vote margin, while the RJD and Congress won in 22 such seats.
