McCain Brain Drain Redux.

"We've seen this movie before,' Obama said at a town hall in Rapid City, S.D. 'A leader who pursues the wrong course, who is unwilling to change course, who ignores the evidence. Now, just like George Bush, John McCain is refusing to admit that he's made a mistake.'" One more from the past week: He already has trouble distinguishing Sunni from Shia. Now, it seems, GOP nominee John McCain is woefully unaware of our current troop levels overseas, and yet -- like a certain prez we could mention -- even refuses to admit he made a simple error. Uh, been there, done that.
