What do Rosie O'Donnell and George W. Bush have in common? They're both stupid, according to Donald Trump.

Trump on Rosie to the Associated Press: "I've exposed Rosie for what she is: a very dumb human being. She's got no intelligence, but I've known that for a long time."

Trump on Bush to Maureen Dowd: "Bush will go down as the worst and by far the dumbest president in history."
