I think as we interpret him and frankly as the world learns to interpret Donald Trump, are these just words that are enigmatic things floating on air or are they actually shifts in policy and will they change moment by moment, day by day without any underlying connection to the actual stuff of governance? I don't know.

I think Romney's foreign policy is sensible.

I learned I'm not a science writer. I'm not very good at describing how something is happening. I try to describe "So What?"

If Donald Trump is just tweeting about a union guy, then he's just being the bully we have seen. But if he uses the power of the presidency to back up some of those tweets and he's really, really coming down with a hammer on people he doesn't like using the power of the presidency, then we're seeing something very new and very different.

Emotion is the foundation of reason.

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.

Republicans are living in a hermetically sealed Republican universe, just as Democrats are. And so they're responding to their own universe, even if it leads to electoral downfall.
