[Ted Cruz] is changed his mind, decided it`s in his best interest to be for [Donald] Trump, which what that says to me is Ted Cruz is a totally craven politician and will say anything to win, but isn`t even good at it.

I think the immigration thing has really stuck to Marco Rubio. He was on the wrong side of what`s emerged as probably the most important issue for the conservative base.

I thought there was something in Ted Cruz`s dignity that prevented him by endorsing a candidate like that, because that was the best explanation of what he did.

Marco Rubio is really to the right of Chris Christie, when Jeb Bush and John Kasich and he hasn`t been able to pull away from them.

I think [Donald] Trump is going to try to be fairly low key, but the problem is that I don`t think he is going to very well with [Hillary] Clinton attacking him fairly relentlessly for 90 minutes.

There was a whole set of issues that the other Republican candidates couldn`t go after Trump that hard on. They had this difficult position where they were trying to knock Trump down while appealing to the voters who liked a lot of the outrageous things about Donald Trump.[Hillary] Clinton is giong to have no such restrictions. She`s going to attack him on a wide variety of fronts and I don`t think Trump is going to deal very well with being attacked in that way.

I thought it was remarkable in July [2016] when he pointedly declined to endorse Ted Cruz at the Republican convention, because I thought that was not in his political best interest.
