One thing I liked about the Bush/Gore debates is that it was obvious both men loathed each other and they didn't care who knew it. That liberated them, for good and ill. By contrast, for all the characteristically ponderous huffing from Bob Schieffer about "negative campaigns", McCain was never able to cast aside the Senatorial collegiality and really stick it to Obama. Why couldn't he have used the s-word - "socialism"? Why couldn't he have said that his opponent is a perfectly pleasant fellow but he has an all but blank resume so all we have to go on is...
