POW! Obama drops a bomb of an ad on McCain's ass this week capitalizing on the Arizona senator's confusion over the number of homes he owns. Money shot: "Maybe McCain thinks this economy is working...for folks like him. But how are things going...for you?"
THAT is a hay maker.
BONUS points for the two subtle nods to McCain's age with refernces to "he doesn't even remember" and showing him tooling around in a golf cart with George HW Bush. Choice!
