Donald Trump is not an unintelligent man.

We're not being invaded by undocumented immigrants who are coming to kill police officers and commit crimes. And I don't think most Americans think it's true.

[The Republicans] looked at basically the failed wars and they said, oh, this, us being the policeman of the world, that is not working.

Basically, global capitalism, basically to support it, or is it to be opposed? Is international order to be supported, or is it to be opposed? Republicans have taken a very clear line.

To me, the fundamental thing - well, I guess I see a lot of people debating in the wrong way. A lot of the debate is, should we go to the coasts, should we go to the center, should we go to the left, should we go to the right?

The final thing the Tea Party had was, they fed into the philosophy that Donald Trump now embodies. So they had a different view of how the world should be governed. And so they had a lot of things that we didn't appreciate going for them as time went by.

If Mitt Romney had got the percentage Ronald Reagan did of Hispanics, he would have defeated Barack Obama.
