The principal challenger, the Indian National Congress, accounted for four of these victories, while regional and minority-based parties such as the Raijor Dal, All India United Democratic Front, and All India Trinamool Congress split the remaining seats.

The scale of defeat in several constituencies was striking. In Samaguri and Dhing, the BJP candidates lost by margins exceeding one lakh votes, indicating strong consolidation of opposition votes. Similarly, Dalgaon delivered the party its worst setback, with a margin of over 1.3 lakh votes in favour of the AIUDF.

A notable feature of the results was the continued dominance of regional leadership in select pockets. In Sibsagar, Raijor Dal president Akhil Gogoi retained his seat, underlining his sustained grassroots appeal in Upper Assam despite the BJP’s statewide surge.

In Barak Valley, the Congress managed to hold ground in Dhubri and Karimganj North, suggesting that the BJP’s expansion in the region still faces structural limitations. Meanwhile, lower Assam constituencies like Mandia and Birsing Jarua saw victories by AITC and Congress candidates, respectively, reflecting a fragmented but effective anti-BJP vote.

Below is a constituency-wise breakdown of the BJP’s defeats:

Taken together, these results point to a clear electoral pattern: while the BJP has consolidated its dominance across large parts of Assam, it continues to face stiff resistance in constituencies with distinct socio-political dynamics—particularly those with high minority populations or strong regional leadership.
