The National Democratic Alliance appears to have secured a commanding lead in the 243-seat assembly race in Bihar, and a senior minister has publicly declared the alliance’s next target as West Bengal. Early trends show the NDA crossing the 122-seat majority threshold with indications of 145–155 seats, while its opponent, the Mahagathbandhan, trails with just over 70 leads. The tidy lead underlines the hold of the ruling coalition in Bihar, featuring Nitish Kumar’s party and the Bharatiya Janata Party. According to Giriraj Singh, the alliance’s “next target is Bengal”, underscoring the BJP’s strategic ambition to expand its influence in the eastern state. Mr Singh remarked that Bihar’s electorate rejected “chaos, corruption or loot” and signalled that the voters of Bengal should expect a similar stance.
The Bihar contest was marked by a turnout of approximately 67 per cent—the highest in the state’s history—fuelled by aggressive campaigning, caste‐based mobilisation and relentless messaging around governance and development. The NDA rested its campaign on continuity under Nitish Kumar, while projecting a hardline posture on law and order and migration. The Mahagathbandhan sought to challenge the coalition by focusing on youth unemployment and alleged anti-minority bias under the ruling bloc. Key seats such as Mokama and Tarapur found early leads for the JD and BJP respectively, emphasising the alliance’s strength in strategically crucial constituencies. The Mahagathbandhan’s inability to consolidate its castes proved a liability even as the newcomer Jan Suraaj Party made a marginal local impact.
In Bengal the BJP faces a far tougher challenge. The state’s ruling All India Trinamool Congress, led by Mamata Banerjee, holds a strong organisational network, deep roots in local politics and the support of key minority blocs. Exit-poll data from the Christian Science Monitor, Financial Times and others show the BJP struggled to cross the 100-seat mark in the 294-member legislature in previous contests, with the TMC dominating 200+ seats in 2021. One BJP strategist observed that achieving “double-digit growth” in Bengal would mark a tactical victory even before considering government formation. While the union minister’s ambition reflects the alliance’s national outreach, analysts warn the BJP must first overcome entrenched regional power structures, narrow vote margins and an electorate sceptical of the party’s promises in the eastern states.
Migration and voter-list controversies add further complexity. The Bihar election became a flashpoint for debates over alleged purging from electoral rolls—with opposition parties accusing the election commission of disenfranchising poor and marginalised communities. The Financial Times flagged that nearly 10 per cent of Bihar’s 74 million voters were removed from the rolls, a claim vehemently rejected by the commission. Mr Singh has extended similar rhetoric to Bengal’s border districts, claiming infiltration from Bangladesh is reshaping demographics—a theme long advanced by BJP leaders in the state. Critics suggest this issue could alienate moderate voices if perceived as communal or exclusionary.
Political scientists point to a dual logic behind the NDA’s Bengal ambition. First, replicating the Bihar model of alliance politics and social engineering — leveraging OBC, EBC and SC voters — could provide the BJP with an incremental margin in peripheral districts. Second, consolidating power in Bengal would strengthen the alliance’s position ahead of the 2029 parliamentary elections, adding weight to its northern and eastern footprint. Nevertheless, veteran campaign observers caution that Bengal’s intensely localised political culture, loyalty to the TMC and episodic violence in border areas mean any quick breakthrough remains improbable. The ruling TMC has begun preparing defensive tactics, emphasising grassroots mobilisation, baby-care schemes for women, and capital-intensive infrastructure projects to blunt the BJP surge.
