Congress and Janata Dal (United) stronghold constituencies have registered the sharpest rise in voter turnout in the 2025 Bihar Assembly elections, while Rashtriya Janata Dal (RJD) bastions have seen comparatively smaller gains, a Moneycontrol analysis shows.

A stronghold is defined as a constituency that a party has won in three consecutive elections.

Congress tops the turnout table

Across all such seats, Congress strongholds posted the biggest jump, with average turnout climbing to 80.2 percent in 2025 from 63.6 percent in 2020, a gain of 16.6 percentage points, the highest among major parties.

The party has just two stronghold seats in the state: Kishanganj (79.84%) and Kasba (80.56%), both in the Seemanchal–Koshi belt, which now sit near the top of the state’s turnout table.
