Bihar Assembly Election Results 2025: How alliance consolidation, vote fragmentation gave the NDA a landslide win - The Hindu

The National Democratic Alliance's (NDA) sweeping victory in the Bihar Assembly elections, securing over 200 of the 243 seats, represents more than just electoral dominance: it exemplifies how India's first-past-the-post system can magnify vote share advantages when party systems consolidate around two principal alliances.The arithmetic tells a compelling story. The NDA secured 47.2% of the vote while the Mahagathbandhan (MGB) obtained 37.3%, a gap of nearly 10 percentage points. While significant, this margin alone doesn't fully explain the NDA's bumper harvest of seats.
