One last thing on the campaign finance kerfuffle, which only has about another 24-48 hours to go before it wheezes out entirely. The basic grievance that McCain's surrogacy has levelled against Obama is that this episode just proves that he's the sort of politician who wants to win at all costs. Of course, there's so little at stake in that "cost" that it's hard to manufacture the sort of umbrage you'd like in the public. Still, I have to say to the GOP: Keep on telling the public that Obama will do whatever it takes to win. It's going to be of great use to me every time I make the case that the same hunger to win also applies to high-level negotiations with Iran.
