Importantly Karnataka people are seeing the happenings of JD(S) and Gowda. They are also watching what Gov is doing and how Central govt responds.
I think BJP has built up good facewhen kumaraswamy was CM and wants to take CM post and do good things that could enhance its image. It could announce a slew of very good measures/policies and then even JD(S) pulls out or Central govt does soe mischief, its going to be advantage BJP.
