Funny you would say that. I'm all for his messages - Two Americas was a great one - but it's his (lack of) skill in presenting them that left me cold, specifically in the debate. I expected a trial lawyer to be much better at making arguments and poking holes (no, not with daggers) in the opposition. He let lots of lies fly right past him without so much as an objection.
I agree that VP debates are meaningless - insofar as their effect on the election outcome. But as a measure of the communication skills of the participant, I think they're perfectly legit.
