A bit late to the game, I know, but a few unsorted thoughts:
1. It's hard to disagree with the CW: this was a good pick, and almost certainly the best one Obama had available to him once Jim Webb took his name out of the running. Biden's tough, and loud, and knows stuff, and he and Obama will be able to play a nice little good cop-bad cop routine with McCain and whatever poor sucker has to share the stage with Talky Joe.
2. Then again, Biden's a thug, and he won't shut up, and he's a know-it-all, and depending on McCain's veep pick the junior circuit debates could end up looking like an LAPD interrogation session gone wrong. He also has a penchant for saying stupid stuff that sometimes comes back to haunt him. Hopefully -- or not, depending -- whoever taught Obama to speechify will be able to put a little polish on ol' Joe, and teach him when to hold his tongue.
3. Now the ball's in J-Mac's court. Where to turn? Perhaps better to opt away from an unpolished noob, though a Palin pick -- which could play up Biden's thuggish tendencies and serve as a reminder of the choice Obama didn't make -- would be intriguing to say the least. (But is she still in the running? Does she have the necessary knowledge and composure? Don't ask me - I'm the guy who didn't know the difference between the real Orson Swindle and the fake one.) In any case, someone smart and quick-thinking enough to resist and dodge, and with enough class and charm to show up Biden's -- ahem -- occasional lack thereof. And if it's Romney ... well, then I really might end up finishing that dissertation.
