I would amend your description. Bush II - dumbest man ever born (until the next republican is elected).
I agree. I thought about making a very similar point by listing Carter, Clinton and Obama each as “The most brilliant man ever elected president”. The portrayal of these people by the press is just cartoony. It still staggers me that a guy with a degree from Yale, an MBA from Harvard, a man who can fly a jet, with a successful track record in state-level politics and in business, who runs two successful campaigns for president, can be portrayed as the dumbest man ever born. But there it is.
