1). No slam dunk. Neither Kerry nor Bush screwed up especially, except in that they were both a little slow to hit really hard, at least by the hyper-vendetta standards of the blogosphere. I would've drilled down on Bush's evasion of the Putin question, myself - and I'm voting for the guy in November. Likewise, Kerry left himself open a couple of times. Dunno if all of this is a bug or a feature.
2). For an event supposedly designed for swing voters, there was a lot of base-stroking involved.
3). It apparently seems quite the thing to mix debate-watching and beer-drinking. Go figure.
