.In the wake of the 2025 Bihar Assembly Elections, newly released data from the Election Commission of India (ECI) has sparked intense discussion regarding the correlation between electoral roll revisions and poll outcomes. A central finding of this data is that the National Democratic Alliance (NDA) secured victory in four out of the five constituencies that saw both the highest and lowest voter deletions during the Special Intensive Revision (SIR).
The Scale of Voter Deletions
The Special Intensive Revision (SIR) was a rigorous exercise conducted by the ECI to clean up electoral rolls. While the opposition, led by the Congress and RJD, raised concerns about large-scale deletions, the final data shows a complex picture.
In Gopalganj, the constituency with the highest number of deletions, the voters’ list shrank significantly from 3,52,054 to 2,95,261—a reduction of over 56,000 voters. Despite this massive shift, the BJP candidate, Subhash Singh, won the seat by a margin of nearly 28,900 votes. Similarly, in Purnia and Motihari, which saw deletions of 50,767 and 49,747 respectively, the BJP emerged victorious with substantial margins.

NDA’s Dominance Across the Spectrum
The trend was not limited to areas with high deletions. In the five Assembly Constituencies (ACs) with the lowest net deletions—Darbhanga, Chanpatia, Bettiah, Dehri, and Mahua—the NDA again showed its dominance. The BJP and the Lok Janshakti Party (Ram Vilas) won two seats each from this group.
This suggests that the NDA’s success was not tied to the specific volume of voter removal. According to the ECI datasets, the fact that the NDA won four out of five seats in both extreme categories is largely proportional to its overall 83% share of the 243 seats in the Bihar Assembly.
The Congress Exception
While the NDA swept most of these categories, the Congress party managed to secure a few notable victories. In Kishanganj, a seat in the Muslim-dominated Seemanchal region, approximately 42,940 voters were deleted during the SIR. Despite this, Congress candidate Qamrul Hoda defeated the BJP’s Sweety Singh by a margin of over 76,000 votes.
The Congress also won in Chanpatia, which recorded the second-lowest number of deletions in the state. These results indicate that high or low deletion rates did not guarantee a loss for the opposition in all contexts.
Voter Turnout and Demographic Factors
The ECI data also highlighted the impact of voter participation, particularly among women. Incentives like the ₹10,000 transfer to women’s bank accounts were seen as a major factor in the NDA’s landslide victory. However, high women’s turnout did not always favor the alliance. For example, the All India Majlis-e-Ittehadul Muslimeen won three of the five seats with the highest women’s turnout (Kochadhaman, Baisi, and Amour).
Conversely, in seats with the lowest overall polling percentages, such as Kumhrar and Bankipur in Patna, the BJP maintained a stronghold, winning four out of the five lowest-turnout seats.
Conclusion: A Result of Broad Support
The analysis of the SIR deletions suggests that while the revision process was extensive, the electoral outcome was driven by broader political factors rather than just the modification of the rolls. The NDA’s ability to win in constituencies with both the maximum and minimum deletions reflects a wide-reaching mandate that transcended the controversies surrounding the voters’ list. As Bihar prepares for a record tenth term under Nitish Kumar, these datasets provide a clearer view of the 2025 electoral landscape.
