Nitish Kumar and the Arithmetic of Power

From caste coalitions to a third-front disruptor, the veteran Chief Minister faces his most complex electoral test yet.

The announcement of dates for the Bihar Assembly election has thrown the state’s political machinery into overdrive. Rallies, public meetings and social media blitzes are saturating the airwaves, while conversations in tea stalls, markets and drawing rooms are charged with speculation about the next government. Bihar, a state accustomed to high-stakes electoral battles since the Mandal-era politics of the 1990s, is bracing once again for a contest defined by arithmetic, alliances and leadership images.

Bihar has often been a laboratory of caste-based politics. The rise of Lalu Prasad Yadav and the Janata Dal reshaped the political landscape, empowering the backward castes and Muslims while challenging the erstwhile dominance of upper-caste elites. Nitish Kumar emerged as a counterweight to Lalu’s charisma, emphasizing governance, development and law-and-order, while maintaining strategic alliances with the Bharatiya Janata Party (BJP) to consolidate non-Yadav backward classes and upper-caste voters. This historical context underpins the 2025 electoral arithmetic, where old patterns intersect with contemporary concerns.

The Nitish factor

At the heart of the ruling coalition, the National Democratic Alliance (NDA), is Nitish Kumar. Having served as Bihar’s Chief Minister for nearly two decades, Nitish remains a stable and familiar presence in the state’s politics. His reputation as ‘Sushasan Babu’ (Mr. Good Governance), his stewardship of the statewide prohibition policy and his image as a clean, reformist leader remain largely intact. Opinion polls suggest that the NDA maintains a modest but consistent lead, even as the Mahagathbandhan (or ‘Grand Alliance’) leverages its Muslim-Yadav vote base and Tejashwi Yadav’s youth-centric leadership to present a formidable counter.

The NDA’s current coalition comprises the BJP, JD(U), Chirag Paswan’s Lok Janshakti Party (Ram Vilas), HAM (Hindustani AwamMorcha), and several smaller allies. Nitish Kumar has already been declared the alliance’s chief ministerial candidate, removing ambiguity over leadership. The BJP commands a strong base among the upper castes, while Nitish’s deep reach among Extremely Backward Classes (EBCs) and Kurmi-Koeri communities complements this. His prohibition policies, women’s employment schemes and financial assistance for self-employment have further cemented his appeal among female voters.

Nitish’s image is also anchored in governance reforms that have outlasted political rhetoric. From the Janani Suraksha Yojana improving maternal health to infrastructure initiatives linking remote districts, his political persona is intertwined with tangible achievements. This record, combined with a perception of relative administrative integrity compared with previous regimes, gives the NDA a distinct advantage in the perception battle.

Chirag’s comeback

Chirag Paswan’s return to the NDA fold marks a reversal from 2020, when his campaign slogan “Modi se bairnahin, Nitish ko khairnahin” (No enmity with Modi, no mercy for Nitish) caused significant disruption within the JD(U). Today, his presence promises to consolidate the Paswan vote, which constitutes roughly five percent of Bihar’s population, particularly across thirty-eight reserved constituencies. Combined with the BJP’s upper-caste support (around fifteen percent) and Nitish’s EBC constituency (over thirty percent), the NDA’s caste arithmetic provides a sturdy platform; in the 2024 Lok Sabha elections, it translated into forty-five percent of the vote share for the alliance.

Chirag’s reintegration highlights the cyclical nature of Bihar politics. Historically, the Paswan community has oscillated between major coalitions, reflecting both its demographic significance and its mobilising capacity. This return could solidify Dalit support for the NDA, especially in constituencies where fragmentation previously allowed opposition gains.

On the opposite side, the Grand Alliance’s core rests on Muslim-Yadav voters, constituting approximately thirty-one percent of the electorate. Under Tejashwi Yadav, the alliance emphasizes youth outreach, employment, and inflation as key issues. Tejashwi’s appeal is amplified by his image as a young, dynamic leader contrasting with Nitish’s seasoned persona, projecting the narrative of generational change. Certain non-Yadav OBC and Dalit communities, such as Ravidas and Musahar, have shown support, though the alliance’s hold over non-Paswan Dalits and EBCs remains tenuous.

Historically, the Mahagathbandhan emerged in Bihar as a counterweight to NDA dominance, drawing inspiration from earlier coalition politics that united regional players against entrenched incumbents. Its current strategy seeks to revive that formula, leveraging both the emotional resonance of anti-incumbency and the organizational network of regional parties. However, the alliance must overcome challenges in outreach to women voters and communities outside its traditional core to convert discontent into decisive victories.

The third front

Adding complexity to the electoral calculus is Prashant Kishor’s Jan Suraj Party. Known for its meticulous micro-targeting and grassroots campaign building, the party has established a presence village by village. Though its strength is insufficient to form a government, it can chip away at the NDA’s support, particularly among Nitish’s EBC voter base. Kishor’s entry reintroduces a variable that could significantly shift seat tallies, echoing past instances in Bihar where third-party players disrupted established vote patterns.

The Third Front also symbolizes a growing national trend of professionalised campaign strategies that emphasise data analytics and behavioural insights over traditional patronage politics, something that could influence voter turnout and preferences in unpredictable ways.

After nearly two decades in power, anti-incumbency sentiment is inevitable. Surveys indicate public dissatisfaction over unemployment, corruption, land disputes, and perceived declines in law and order. Criticism of Nitish’s age and frequent shifts in alliances has further amplified opposition narratives. Yet, the government has countered with a flurry of welfare measures in recent months: increases in old-age pensions, direct benefit transfers of ten thousand rupees to 7.5 million women for self-employment, 125 units of free electricity per household, stipends for unemployed youth, and enhanced allowances for frontline health workers like ASHAs and Mamatas.

Analysts estimate that if the NDA can secure an additional three percent of women’s votes, Nitish could reach 170 seats in the 243-member assembly.

The impact of these policies is as much emotional as economic. Women who benefited from Nitish’s flagship bicycle scheme between 2005 and 2010 are now adult voters whose political memories intertwine with his governance. This enduring personal connection fortifies what analysts term the NDA’s ‘empowered supporter segment.’

The Grand Alliance has focused on employment, education, and corruption to retain its core base. Rahul Gandhi’s Voter Rights Yatra and Tejashwi Yadav’s active campaigning target young voters, aiming to create a generational contrast with Nitish’s seasoned leadership. Yet penetration among non-Yadav OBCs and women remains limited. While discontent exists, translating it into a decisive wave for change remains the challenge. Historical patterns in Bihar suggest that scattered anti-incumbency rarely produces dramatic swings unless backed by disciplined organisation and cross-community alliances.

Image vs arithmetic

At its core, the 2025 Bihar election is a contest between the weight of Nitish Kumar’s persona and the arithmetic of caste alliances. The NDA brings together upper-caste voters, EBCs, women, and the Paswan community; the Grand Alliance relies on a strong Muslim-Yadav base and youthful energy, but its reach beyond these groups is uncertain. Opinion polls give the NDA a slight lead, projecting 130–160 seats, while the Grand Alliance could secure between 65 and 105.

The final verdict will hinge on how effectively the benefits of welfare schemes convert into votes. Second, which camp bears the brunt of the Third Front’s impact. Which narrative - experience and governance versus youth and change - resonates more powerfully with voters in the last weeks of campaigning.

Nitish Kumar’s decades of governance and carefully curated image confront the persistent anti-incumbency that naturally accrues over twenty years. The NDA leans on the solidity of caste coalitions, women’s support, and welfare programs while the Grand Alliance seeks to harness discontent and youth energy. With the Third Front poised to play spoiler and the electorate’s mood notoriously difficult to gauge, an unpredictable contest seems to be in the offing.
