From the Cleveland Plain Dealer:

President George W. Bush's campaign for a second term got a big break last week from the nation's historians. Responding to a national survey by George Mason University's History News Network, 81 percent of the 415 historians who expressed a view of the Bush presidency so far classified it as a failure and 12 percent see it as the worst presidency in American history.

But since Bush is Lord of the C-Students, I suppose this should be expected.
