The major players in Bihar are the ruling alliance of the Janata Dal-United and the Bharatiya Janata Party, the Opposition alliance of the Mahagathabandhan led by the Rashtriya Janata Dal with the Congress and three Left parties.

In 2015, the JD-U was in alliance with the RJD and the Congress and defeated the BJP quite comfortably.

This time around, the JD-U is back in the National Democratic Alliance and looking promising to win the elections.


Rediff Labs analysed the 2015 assembly election results to develop a Sentiment Meter for the 2020 battle in Bihar.

A mathematical model is used to calculate how seat distribution will be altered as sentiment/percentage of votes towards a contesting political party changes.

Based on the change, each constituency is marked with the winning party.

A swing represents that the victory margin is close to the runner-up party.

Move the pointer on the Sentiment Meter (depending on who you think will get more votes) towards the political parties to see how the outcome is likely to change.
