"Well... it's seven. Seven houses."

I'm not a fan of negative political ads.

But they work, and Democrats traditionally suck at them. And John McCain has pulled even in the polls this week largely as a result of the success of his negative ads.

This one from Obama is surprisingly pointed. For something I don't really condone, I respect this ad:



Also a pretty strong dig at McCain's age via an attack on his memory. I'd call that low, but no lower than anything McCain's done.
