So what does everybody expect tomorrow night?
Both candidates are very polished speakers so I don't think we'll see either make any major mistakes. It might be uneventful with a lot of statistical claims that will keep the fact-checkers busy the rest of the week.
You might see Obama pull the trigger on some kind of Libya retaliation the following day, kind of a wag the dog, to deflect the foreign policy criticism he's bound to catch from Romney.
I also don't think there will be any "zingers" thrown by either Presidential candidate. That can backfire and make them look bush-league. That kind of stuff with probably happen though in the Biden / Ryan debate.
