I just think, realistically, there's a lot of room outside the Trump populist right and the Bernie-Sanders-Elizabeth-Warren populist left. There are a lot of us who believe in open trade, open borders, a dynamic forward-looking economy, not a nostalgic economy, but do want to provide a significant level of social service or sort of economic Milton Friedman foreign policy, Ronald Reagan domestic policy, Franklin Roosevelt. And there's a lot of room in the center.

Who could have predicted this, that the presidency is kind of a hard job? Nobody knew that. I also like the fact that Trump is a detail-oriented person. I find his interviews amazing. He's actually kind of remarkably candid.

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.

Personally, I think Mitt Romney would be a great secretary of state.

For the Republican Convention, I think of Trump's speech and sort of the darkness, the fear of crime, the need for a strong arm really, and so that one core theme.

America has an important role to play as the world leader in creating a global order, free trade, free waterways, free commerce, free movement of people. That happens because of U.S. military might.

The zooming wealth of the top 1 percent is a problem, but it's not nearly as big a problem as the tens of millions of Americans who have dropped out of high school or college. It's not nearly as big a problem as the 40 percent of children who are born out of wedlock. It's not nearly as big a problem as the nation's stagnant human capital, its stagnant social mobility and the disorganized social fabric for the bottom 50 percent.
