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.

Now the Republicans have a very low-scale, by economic standards, base. Donald Trump has.

The White House, as Warren Harding said, and I think accurately, is an alchemist. We find out the strengths, the weaknesses and the smarts and the dumbs of whoever those occupants are under the pressure of the presidency.

The pattern of American presidential elections is that the more optimistic candidate, whether it's John Kennedy and let's get America moving again, Ronald Reagan, it's morning in America, or Barack Obama, yes, we can, always wins, or nearly always wins.

I do think, over the last years, a lot of Republicans have decided it's not working, what the party believed in, free trade, global capitalism, open borders.

It's fine to be an activist, but you're not - if you're not putting up candidates, if you're not getting political, if you're not in your party, then you're probably not going to have long-term change. You will probably dissipate.

Donald Trump is to traditional values what I am to marathon running.
