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.

It sure looks like [Vladimir] Putin did this [hack DNS site]. And we all need to take this seriously.

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

On the question of opposition, I think there are - when you want to send a signal if you're on the Democratic side that this is a very right wing cabinet at odds with so much of what [Donald] Trump said. And it's also going to be fascinating to see if your Republican Party in the congress actually goes along with those aspects of the Trump plan that are designed to raise wages.

When [Republicans] say they can reduce taxes and trim deficits at the same time, they are either deluded or deceptive, and they are playing voters for fools.

In the Trump language, words change their meaning day by day depending on his own political needs.

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.
