You can knock Obama all you want, but the one thing you can't say about him is that he's stupid. This guy graduated magna laude from Harvard Law!
Bush, on the other hand, is a veritable dimwit. His IQ of 115, while above average for the American population as a whole, is incredibly low for a President of the United States. By comparison, my IQ is far, far higher than Bush's, and I'm nowhere near being a head of state. If your average guy on the internet is literally more intelligent than the most powerful man in the world, you've got a problem.
