BJP campaigned on supporting Nitish Kumar as CM even if the BJP wins more seats than JD(U). Now that BJP will end up with something like 74 MLAs vs 43 MLA for JD(U) puts BJP in a bind. The will face pressure from within to put in a BJP CM especially when the large drop of JD(U) MLAs represents a vote of no confidence in Nitish Kumar.
I guessing JDU is going to claim that JDU could have been the largest party without LJP splitting the NDA vote in JDU seats.
