I wasn't shocked to hear Sarah Palin accuse Obama of hanging out with terrorists yesterday (the Ayers reference), as many GOP pundits have said that the McCain campaign has to go ape-shit negative on Obama to have any chance of winning next month. But if McCain brings that point up in Tuesday's debate, I hope Obama hits back, for example by pointing out that McCain's campaign manager and senate chief of staff are both former senior lobbyists for Freddie Mac. That should resonate with a few voters.
