There's a ton of academic literature that shows people are much more critical of female leaders than they are of male leaders. They're much less tolerant of female ambition, much more threatened by female power.

Foreign policy is a little bit like a guy who goes to Las Vegas. If you win too much, then you eventually bet the mortgage. You start to think you are infallible.

It's easy to see why conservatives would be salivating at the thought of a Hillary primary challenge. Presidents who face serious primary challenges—Ford, Carter, Bush I—almost always lose. The last president who lost reelection without a serious primary challenge, by contrast, was Herbert Hoover. But in truth, the chances that Obama will face a primary challenge are vanishingly slim, and the chances that he will lose reelection only slightly higher. No wonder conservatives are fantasizing about Hillary Clinton taking down Barack Obama. If she doesn't, it's unlikely they will.

I think ultimately Obama's ability to rebuild America's image in the world will depend less on his personal good will and more his ability to rebuild an American economic model that seems stable and humane and dynamic.

I've heard people in the Middle East tell me that the most inspiring thing for them as people struggling against dictatorship in the Middle East is the memory of the civil rights movement.

I think the most inspiring thing that Americans can do for the rest of the world is struggle against the evils in our own society.

When you talk about the security and safety of average Americans it doesn't do average Americans a lot of good to expand America's military footprint if the daily lives of average Americans are being undermined by the fact that we're no longer able to compete in a global economy. I think that's the kind of human security we have to pay more attention to.
