The way he lies so easily caused me to wonder if he even always knows that he is lying. I thought perhaps he's lied so much that he even believes his lies; the kind of person who can pass a polygraph test while lying their butt off. I've known a couple of people who were pathological liars/compulsive liars (whatever the correct term is), and I was thinking bush might be the same type of person.

I thought sociopaths were intelligent, but I'm not sure if that's correct or not. But as was just said, the idiocy may not be the truth.
