The things that make them similar - their machismo, their expansionary braggadocio - is going to turn them I think into bitter and dangerous enemies. We will look back on this moment where we thought Vladimir Putin and Donald Trump were sort of close as a moment of bitter irony, when they get into a schoolyard display against each other, amping up each other's worst tendencies and putting the two countries in some sort of scary position.

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?"

I think Donald Trump is going to find it very hard to do the kind of massive change he wants.

We still are America though. We're still a country that is a country of social mobility. We're still a country of immigrants. We're still a country with common ancestors. And reviving the civics of America and the idea that we're going to be united, at least not right now, but in some common future, and talking in that hopeful way that Martin Luther King did, that Abraham Lincoln did, seems to me that's the way.

President Obama was the first president not to abide by the limits in the general election.

For us going forward, it's to not reverse the dynamism of American society and the diversity. It's to pay attention to the people who are being ruined by it, and so this doesn't happen again.

For those of us who believe in it, there has to be a movement that says, "We still believe in trade. We still believe in international engagement for America. But for those losers or those who are suffering, we've got your back."
