At the national level, the Bihar result will likely lead to a major reconfiguring of political strategy. Certainly, the Congress and other regional political parties will attempt to forge alliances to counter the BJP, as they did in Bihar. But this may not work in many forthcoming elections - definitely not in West Bengal and Kerala, where the BJP is not enough of a threat to dominant local players like the Left or the Trinamool Congress. Assam, where the BJP made major inroads in 2014, might be an exception. The BJP itself will be doing other mathematics: that of the Rajya Sabha. The NDA might not get a majority in the Upper House in the entire term of the current government. Clearly, the BJP and Prime Minister Narendra Modi will have to reach out to the Opposition if they want to get important laws passed. There is no doubt, therefore, that Mr Modi has been weakened as a result, and will have to treat the parliamentary Opposition with more care than he has needed to do so far.
In any case, given the absence of a chief ministerial candidate, Mr Modi was the face of the BJP in the Bihar election, and he campaigned extensively; the result will dent his political capital, and is a major setback. Certainly, stridency on social issues like reservation and cow slaughter has not helped the BJP. At least in terms of the political calculus, the BJP will have to rethink its hands-off approach while dealing with some of its leaders' irresponsible statements. Much depends on the lessons that the BJP and Mr Modi draw from this setback and the emergence of an alliance of this nature. It is in India's interest that they, and therefore the government, work on conciliating the Opposition so that the government's ability to act on economic reform remains unhindered.
