The rise of the Bharatiya Janata Party (BJP) in West Bengal over the past decade has been one of the most striking shifts in the state’s political landscape, where the saffron outfit has pushed itself up from a one-time marginal force to emerge as the main Opposition.
The expansion of the party’s electoral base is strongly visible over the last few elections, with its climb north from 17 per cent vote share and 2 seats in the 2014 Lok Sabha polls to 41 per cent and 18 seats in 2019, and from 10 per cent vote share with 3 seats in the 2016 assembly elections to 38 per cent and an impressive 77 seats in 2021.
Not only has the party become a principal challenger of the Trinamul Congress (TMC), it has also built a durable vote base and a visible rightist political culture that now permeates large parts of the once Left citadel.
From a layman’s parlance, the BJP’s most significant achievement lies in occupying the opposition space once dominated by the Left and Congress, effectively turning Bengal into a bipolar contest.
The party now has a stable electoral base hovering above the mid-30 per cent range, anchored in regions such as North Bengal and Junglemahal (forested stretches of four western districts ~ Bankura, Purulia, West Midnapore and Jhargram) and backed by a broader consolidation of Hindu votes cutting across caste lines.
However, despite the significant progress, as the 2026 Assembly election approaches, the BJP appears to be caught between momentum and structural limits as opposed to the entrenched dominance of the Mamata Banerjee-led Trinamul Congress.
The BJP’s organisational strength, while formidable in pockets, remains uneven when compared to the dense grassroots networks of the TMC, particularly in rural South Bengal, where elections are often decided.
However, the party leadership disagrees.
“TMC has been in power for the last 15 years and there is a strong anti-incumbency factor among the people. They cannot openly go against the TMC, but they do want a change and we believe this will be reflected in the EVMs,” BJP candidate and the party’s chief whip in the Assembly Shankar Ghosh said.
The party’s reliance on its central leadership, though electorally energising, reinforces a perception that it is not in sync with Bengal’s linguistic and cultural ethos ~ a narrative its opponents continue to exploit.
Internal frictions between old cadres and defectors, alongside factional rivalries, are other factor.
The electoral arithmetic also presents a structural constraint. The near-total consolidation of minority voters, said to hover around 30 per cent before the ongoing Special Intensive Revision (SIR) of electoral rolls, against the BJP, creates a ceiling that is difficult to breach in a state where such demographics are decisive in many constituencies.
Even with a substantial vote share, the party has repeatedly encountered the problem of conversion ~ losing narrowly in multiple seats due to the vote distribution, while TMC’s spread remains more optimised.
Ghosh, however, differed. He said: “Even if we concede that we fell short in reaching out to the minority communities, particularly Muslims, our vote share still exceeded 38 per cent. A further swing of around five percentage points would be sufficient to bring us to power, and such a shift appears attainable with a consolidation of Hindu votes.”
However, political observers believe that the economic demography of Bengal is far more complex than how the BJP views it.
“The BJP appears to be focusing primarily on consolidation driven by religious sentiment. However, in Bengal, the economic ecosystem often carries greater weight than religious polarisation. In many regions, Hindus and Muslims are directly or indirectly interdependent for their livelihoods; in such contexts, removing a Muslim name from the voters’ list could disrupt these economic linkages,” political analyst Biswanath Chakraborty said.
