The BJP stands today as the most influential political force in the country, yet its dominance is neither uniform nor absolute. In some regions, it exercises near-total control, while in others it relies heavily on allies, and in certain pockets it continues to struggle for a breakthrough. This layered expansion defines the party’s evolving national footprint.
The upcoming declaration of results from assembly elections across five states and Puducherry on May 4 is expected to further test and possibly extend the BJP-led alliance’s political reach.
Strongholds of Dominance in the Hindi Heartland and Western India
The BJP’s most entrenched base remains the Hindi heartland and parts of western India, where it not only competes but effectively sets the terms of political engagement.
Uttar Pradesh, Madhya Pradesh, and Gujarat continue to serve as the core pillars of its strength. In Uttar Pradesh, the BJP secured a comfortable majority in the 2022 assembly elections with over 250 seats and a vote share of approximately 41 to 42 percent, successfully retaining power despite anti-incumbency challenges. Madhya Pradesh witnessed a strong return of the BJP in 2023, where it won 163 out of 230 seats with nearly 48 percent vote share, marking one of its most commanding performances in the state.
Gujarat remains its most secure political bastion, closely associated with Prime Minister Narendra Modi. In the 2022 elections, the BJP achieved a record victory of 156 out of 182 seats with a vote share exceeding 52 percent, effectively transforming the state into a near one-party dominant system.
The party has also consolidated its position in Rajasthan, Chhattisgarh, and Haryana. In Rajasthan’s 2023 elections, it crossed the majority mark with 115 seats and over 42 percent vote share. In Chhattisgarh, the BJP staged a significant comeback by winning 54 out of 90 seats with around 47 percent vote share.
Across these states, the BJP’s vote share often remains at or above 45 percent, creating a winner-takes-all electoral dynamic where a fragmented opposition struggles to mount effective resistance. This consistency is attributed to a combination of ideological mobilisation and welfare-driven beneficiary politics, where direct delivery of government schemes has strengthened voter loyalty.
Expansion Beyond Traditional Bases
Beyond its traditional strongholds, the BJP’s political narrative is defined by its expansion into regions historically dominated by regional parties.
In Odisha, the party transitioned from a marginal presence to a governing force over the past decade. In the 2019 assembly elections, it increased its presence to 23 seats with around 32 percent vote share, emerging as the principal opposition. By 2024, this growth translated into political control, ending decades of dominance by the Biju Janata Dal.
Maharashtra reflects a more complex political evolution. In the 2019 assembly elections, the BJP emerged as the single largest party with 105 seats and a 26 percent vote share. Subsequently, through political realignments, including splits within Shiv Sena and the Nationalist Congress Party and the formation of the Mahayuti alliance, the BJP positioned itself as the central force in governance, ultimately placing its own leadership at the helm of the state government.
A key driver of this expansion has been the party’s strategic outreach to smaller Other Backward Class groups and marginal communities, weakening traditional regional vote banks and reshaping electoral alignments across states.
Coalition Dependencies and Conditional Dominance
Despite its expansive reach, the BJP’s dominance remains conditional in several regions where coalition politics is essential.
At the national level, the current government depends on allies such as the Telugu Desam Party and the Janata Dal (United). In Bihar, while the BJP has strengthened its position significantly, including becoming the single largest party in the 2025 assembly elections with 89 seats, it still operates within a coalition framework. The appointment of Samrat Choudhary as Chief Minister marked the party’s first direct leadership of the state government, following Nitish Kumar’s departure from the role.
Even so, Bihar remains a coalition-dependent state where the BJP does not independently command a majority and continues to rely on partners for governance stability.
In Andhra Pradesh, the BJP maintains a limited electoral presence with single-digit vote share and functions as a junior partner in a Telugu Desam Party-led arrangement.
In the northeastern region, the BJP has constructed an extensive governing network through the North-East Democratic Alliance. In Assam, it holds a strong position with 60 out of 126 seats in the 2021 elections and approximately 33 percent vote share, rising further when allied support is included. However, in states such as Nagaland and Meghalaya, governance is shared with regional partners, and the BJP’s role remains proportionally smaller.
The Unfinished Political Map: Southern and Eastern Frontiers
Despite its widespread expansion, significant regional gaps remain, particularly in southern India.
Tamil Nadu continues to resist BJP expansion. In the 2021 assembly elections, the party recorded a vote share of 2.6 percent, though it has shown incremental growth in certain areas. However, it remains structurally dependent on alliances, particularly with the All India Anna Dravida Munnetra Kazhagam, to maintain electoral relevance against dominant regional forces.
In Kerala, the BJP continues to face challenges in converting vote share into legislative seats. In the 2021 elections, it failed to win any seats despite securing an 11.4 percent vote share, indicating presence without electoral breakthrough.
West Bengal remains a crucial battleground. In the 2021 assembly elections, the BJP made significant gains, winning 77 out of 294 seats with a 38.4 percent vote share, a sharp rise from near insignificance a decade earlier. However, it fell short of displacing the ruling establishment, which secured 215 seats with approximately 48 percent vote share.
The gap between substantial vote share and actual governance control remains central to the BJP’s ongoing political challenge in these regions, where regional identity and leadership continue to play a decisive role.
The evolving national map thus reflects a party in expansion, yet still navigating the limits of regional diversity and coalition politics.
