It's funny, I never thought of clinton as "smart" (although that was always cited by his supporters as one of his biggest attributes). But kerry/edwards make clinton look like a genius by comparison. If there is a pile of dog excrement on the sidewalk, they seem to have an uncanny ability to go out of their way to step on it. For all of clinton's lying, cheating, delusional ways, he would never do any of this stuff.
The ladies still adore him.
He has a photographic memory and the cunning of all psychopaths. That's why he impresses some as "smart". Fools.
