Why not just part company with ABC and empanel a group of thoughtful bloggers like Josh Marshall, Duncan Black (who lives in Philly!), and any number of others; plop HC and BO in front of them; turn on the cameras and liveblogvideo the whole thing?
Note that there is a big difference between the above and the networks taking suggestions for questions from viewers via the net. I'm much more interested in the former than the latter.
OTOH, if we don't have a Democratic incumbent running unopposed in 2012, I may be living in Vilnius anyhow, and it is hard to imagine the Republicans doing it.
