Dumb as a post

As everyone except the vast unwashed electorate (and the press who keep them unwashed) knows by now, St. John McCain confused Sunnis and Shi'as once again yesterday in the Petraeus-Crocker hearings. Mrs. Walldon reports that she heard a physician caller to Air America yesterday saying that failing to remember where you left your car keys is not necessarily a sing of dementia. What is a sign of dementia, the caller added, is when you're holding the keys in your hand and you forget what they're for. John McCain, the caller noted, is holding the keys in his hand and doesn't know what they're for.
