Yes to Cruz. Trump only with a conservative VP.
I think trump is smart enough to know that he will need some one with true conservative pedigree to bring the party together after the convention. trump understands deal making and he knows if he wants to get anything done after elected he cant be fighting both the Democratic party and the republican establishment. My bet is that who ever he chooses for Vice president that it will be someone that has a lot of capital hill experience and will be the least controversial thing he does during the election.
