Trump has picked the more extreme versions of all Republicans so far, the more aggressive. And I think the thing to watch out for is, I could totally paint a scenario where Trump runs an authoritarian regime. I can totally paint a scenario where he has no control over his own government.

My SUV, assuming Hummer comes out with a model for those who find the current ones too cramped, will look something like the Louisiana Superdome on wheels. It'll guzzle so much gas as I walk out to my driveway there will be squads of Saudi princes gaping and applauding. It'll come, when I buy it, with little Hondas and Mazdas already embedded in the front grillwork.

One of the things I think about with Donald Trump is what are his words actually attached to? With Trump, I'm not sure the words have roots. They are emanations of his psyche, but has he thought it through? Is there an argument, is there a policy implication?

We have an international system. We all profit from it. Trade profits from it. Peace. We can travel around the world because of it. And part of that system is certain ideas, the certain ideas you can't invade other countries for no reason. You can't commit genocide. You can't - rogue regimes can't have nuclear weapons, and you can't gas your own people.

The prevailing view is that geniuses are largely built, not born.

We live in a culture that encourages us to be big about ourselves, and I think the starting point of trying to build inner goodness is to be a little bit smaller about yourself.
