West Bengal election results 2026: Why Mamata's defeat is a good news for Congress

The 2026 West Bengal assembly verdict is, on the surface, a straightforward story of Bharatiya Janata Party (BJP )victory at the expense of the Trinamool Congress (TMC). However, beneath that dominant arc lies a more fragmented sub-plot: the TMC’s weakening hold over its traditional social coalitions has not only aided the BJP’s consolidation in several belts but also created limited yet politically meaningful openings for the Congress in pockets of central Bengal.

For a party that drew a blank in the 2021 assembly elections, the Congress’s return of at least two constituencies, Farakka and Raninagar in Murshidabad, marks more than arithmetic improvement. It signals a modest, geographically concentrated revival in a state where the party has been politically marginal for over a decade.

Congress in West Bengal

In Farakka, Congress candidate Motab Shaikh defeated his BJP rival by 8,193 votes, securing 63,050 votes, while the TMC finished a distant third with 47,256 votes.

In Raninagar, Julfikar Ali won a closely fought contest by 2,701 votes against the TMC, with the CPI(M) trailing further behind and the BJP slipping to fourth place. Both seats sit in Murshidabad, a district where electoral competition has increasingly been shaped by multi-cornered contests rather than the traditional TMC vs BJP binary.

How Congress is slipping into the gaps

That vote fragmentation is central to understanding Congress’s limited resurgence. The erosion of TMC’s consolidated minority and rural vote base, particularly in pockets of Murshidabad and adjoining regions, has not translated uniformly into BJP gains. Instead, it has been partially redistributed among smaller regional formations and, in select constituencies, back towards Congress candidates with entrenched local networks.

What is notable here is not a swing towards Congress, but a vacuum effect. Where the TMC’s earlier consolidation breaks down, electoral space does not immediately reorganise into a direct bipolar fight. It fractures first and is then partially reassembled at the local level by parties that still retain organisational memory, however thin, at the booth level.

The result is a paradox. The TMC’s weakening dominance has simultaneously enabled BJP expansion and created isolated competitive corridors for Congress.

This dynamic is reinforced by broader vote share patterns. According to Election Commission data, Congress remains a low-base player at just over 3 per cent vote share, but its impact is disproportionately visible in tightly contested minority-dominated seats where multi-cornered contests dilute TMC margins.

A clearer illustration comes from constituencies such as Baharampur, the long-time political base of senior Congress leader Adhir Ranjan Chowdhury. Here, the BJP secured a decisive win while the Congress finished second, pushing the TMC into a weaker position despite not being the principal beneficiary of the anti-incumbency wave.

For Chowdhury personally, the outcome marks a sharp setback in a constituency he once anchored for decades. Structurally, however, it reinforces the broader pattern: the collapse of TMC consolidation does not translate into a clean transfer of votes to the BJP alone. Instead, the Congress emerges as a secondary absorber of fragmented anti-incumbency sentiment in specific pockets, even when it is not the dominant challenger across the state.

Resetting the hierarchy within INDIA bloc

The reduction of the TMC’s political weight in West Bengal not only reshapes the state’s electoral map but also quietly alters the internal balance within the INDIA bloc. For much of the post-2023 phase, Mamata Banerjee’s positioning within the alliance regarding West Bengal was shaped as much by perception as by numbers, particularly her argument that regional parties with proven records against the BJP were better placed to lead the opposition space than a Congress that had struggled in several key states.

That positioning takes a sharper hit with her own electoral setback in Bhabanipur, where she has lost ground to the BJP’s Suvendu Adhikari. The symbolic weight of a sitting chief minister losing her own constituency compounds the broader weakening of the TMC’s mandate in the state and directly dents her bargaining power within the alliance.

With the TMC’s performance now significantly weakened, that narrative loses some of its immediate political force. The space within the opposition alliance becomes less about competing claims of leadership and more about managing arithmetic cohesion across parties with uneven state-level strengths. In that context, the Congress is no longer operating within the INDIA bloc in a space where it must contend with a rival claimant to leadership on relatively comparable political strength, even as both parties continue to function within the same alliance framework.

A limited opening, not a revival

For the Congress, therefore, Bengal 2026 is not a story of revival in any conventional sense. It is, instead, a story of residual relevance, a party benefiting indirectly from the TMC’s erosion of social coalitions without yet possessing the organisational strength to convert that erosion into a sustained state-wide footprint.

The larger structural reality remains unchanged: the BJP is the principal beneficiary of the TMC’s decline, having consolidated its position as the primary challenger across multiple regions of the state. However, the Congress’s small gains in Murshidabad showed that the breakdown of a dominant party system does not automatically produce a single alternative, but often a scattered redistribution of votes across multiple poles.

In that sense, the Congress has not replaced the TMC anywhere in Bengal’s political hierarchy. But in a state where its relevance had nearly collapsed, even limited victories in Farakka and Raninagar represent something more consequential than numbers, a foothold in a system that had almost written it out entirely.
