Brilliant debate quote

In the last debate McCain acted hostile and condescending towards Obama, continually saying "Senator Obama just doesn't understand..." It was annoying, and Barack did not address it directly. But if there is one thing we Obama supporters have learned, and now John McCain has learned, is that Obama is a fast learner. He didn't forget that quote and obviously wanted to do something about it. And what he did was say this:

"Senator McCain, in the last debate and again today suggested that I don't understand. It's true. There are some things I don't understand. I don't understand how we ended up invading a country that had nothing to do with 9/11."

Brilliant!
