Less than a day after John McCain admitted that he couldn't quite remember just how many houses he has (7, if you're scoring at home), the Obama campaign has put together an ad dinging him for it. That's got to help soothe the fears of Democrats worried about Obama's rapid-response team, no? Also, Jesus Christ, 7 homes? I'm still paying rent on a one-bedroom. I need to marry me some hooch heiress but quick.
