He’s a GOP establishment hack that caved on amnesty and will do it again in a millisecond.
Well if he is they didn’t show that by spending tens of millions of dollars attacking him in the primary, including I believe about $10 million in Florida alone - angry with him for not listening to them and running when it was “Jeb’s turn” as a follow-up to them being angry with him for running against Charlie Crist against their wishes. They only go for him in the end when they have no other choice.
