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.

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.

It doesn't need to be deep and it doesn't need to be a 65-point plan, but just to give some concrete examples of how this economy is going to work for the people that feel right now it's not working for them, and then finally to get to central tension of this campaign. This is a presidential campaign where you have Americans now who want to see change. And Hillary Clinton is the status quo. How can she be both status quo and change?

Hillary Clinton is got to make the case for herself that nobody else can make, and for voters to see somebody who looks more three-dimensional, that's not simply a caricature that had been sort of a part of the American dialogue for the last 25 years.

The ones who are in the Senate have to have a position.

If you're Chris Christie, who is governor of New Jersey, a state that obviously was impacted by 9/11, this gives you an opportunity to talk about how, as governor, you had to deal with terrorism and security issues.

It's never a good time, when you're the president of the United States and your own party is finding lots of different ways to distance themselves from you.
