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.

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.

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.

In the one-on-one it is going to be harder for [Donald] Trump to get away from those sorts of things because there will be more opportunities for Hillary [Clinton] to follow up on those sorts of things. And I also think to your previous point, I think she really does need to induce errors from him because the biggest hazard to Hillary Clinton is that Trump could clear the low bar of acceptability in debate.

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.
