The madman theory can work, but it only works if it's strategic. And I think one of the problems that President Trump faces is people don't really know how much strategy is here and how much is he just sort of talking off the top of his head. And I think North Korea is a really classic case of a potentially insoluble problem, a problem that you have to manage.

A nation that hates politics will not long survive as a democracy.

I actually think there are more Republicans than people realize who would be sympathetic to immigration reform in the rank and file. I think the lesson for Jeb Bush is politicians shouldn't write books with long lead times.

You have this all the way through this cabinet so that I think there are a lot of other things to worry about [Donald] Trump. But in conventional political terms, this is a cabinet that I think is going to have a very hard time delivering to the base that Trump courted in this election.

What I am really worried about is that Donald Trump steps outside norms about, for example, what he does about his business. If he holds on to his business or just lets his kids run it, this opens up enormous possibilities for conflicts of interest.

We have pursued public policies that kind of hold the recovery back, but the private economy is really starting to roll.
