This realization is too late. They should have asserted much early, and shd have insisted on first ministry by BJP and later by the JD-S.
JD-S has always been a fence sitter, and known for ditching parties at the drop of a hat. You all will remember how Mr.Gowda had ditched RK Hegde, Bommai, Dharam Singh. I doubt very much whether JD-S will transfer power to BJP smoothly this time. Already there have been rumours that they are in talk with Congress. Congress, knowing JD-S very well, if they have any shame, should not agreee to any sort of an arrangement with JD-S, and the BJP shd insist on transfer of power at the due date without fail. They shd talk strongly with JD-S. JD-S will enact all kinds of dramas to avoid transfer of power. BJP shd therefore be very careful in getting their rights.
