The people that Donald Trump is putting around him on the Cabinet suggest that he's putting together a very conservative, almost traditionally conservative Republican group around him.

The real problem with Donald Trump is, if you engage him, it will only make things worse. It's like - it's a little bit what you were taught as a kid to not engage the bully, because they will continue to pick on you.

I still think there's some tension . But it's pretty clear that, when the president made his statements as a candidate, he's following through with those as a president.

When Jeb Bush came on the shows and couldn't answer questions about Iraq, and when he looked like he was unsteady, it absolutely solidified the concerns that they had had all along about his skills.

The difference there is that the [Donald] Trump number on change is so much larger than the lead that the other two have in their lanes. And that's going to be the challenge for those other two going forward. The other challenge for Marco Rubio, and this assumption that you're just going to get all those Bush and Kasich voters.

The only problem with the "children of Reagan" line is it reminds you that Marco Rubio is the young candidate.

Usually, you do a shakeup because you know that you have a problem or you gaps and you're going to fill those gaps.
