I have no idea how intelligent Bush actually is. As I said, I have heard that his iq isn't all that high. It obviously is above average (or at least I'd like to think that the president of the world's most powerful nation is a few steps above average) and, as you said, his off-the-cuff remarks are a total disaster and good for a joke or two.

I still stand that the joke makes more sense against Bush than Bill and Hillary. In reality, it is a joke that really shouldn't be applied to any of presidential candidates. They have shown a level of intelligence that hasn't been around in many a campaign.
