Caste, however, remains the key to political power in Bihar, where people are said to vote not for the candidates but for their caste. The savarna castes dominated politics in the decades after Independence when the first CM (1946-61)—Krishna Singh (Sinha) a.k.a Shri Babu—belonged to a Bhumihar (landholding, instead of priestly, Brahmin) caste. Rajputs and Brahmins, too, were partners in power. Later, the Dalits and the backward castes—who number more than the other castes in Bihar, comprising 19.5 per cent and 63 per cent of its population, respectively—were mobilised with Karpuri Thakur as their voice. After 1990, the Mandal movement changed the course of politics as regional parties developed alongside the emergence of Dalit and backward caste leaders with a mass appeal. Since the 1995 election, Bihar politics has revolved around Lalu and Nitish. All the savarna castes together comprise only around 10 per cent of the electorate, and the Jan Suraaj Party has no new equation to break the prevalent combinations of the backward castes.
