I cannot imagine how you Rate John Adams, James Madison, and Andrew Jackson as worse presidents than the cokehead partyboy moron Bush.
Was Bush using cocaine in the White House? His grades were better than Kerry's (C+ vs C). Don't think he can be called a moron. Besides, some of our worst presidents have scored highest on the IQ scale. Not sure intelligence is as important for a president as leadership ability and the ability to adapt to changing conditions.
