Krugman. Brilliant. Again.

In two paragraphs, he sums it all up:

Since 2000, we've seen what happens when people who aren't interested in the facts, who believe what they want to believe, sit in the White House. Osama bin Laden is still at large, Iraq is a mess, New Orleans is a wreck. And, of course, we've done nothing about global warming.

But can the sort of person who would act on global warming get elected? Are we — by which I mean both the public and the press — ready for political leaders who don't pander, who are willing to talk about complicated issues and call for responsible policies? That's a test of national character. I wonder whether we'll pass.
