Biden-Ryan VP Debate - Who won?

Let me first say that I did not watch the debate in its entirety. Why? Well because they are veeps, not presidential candidates. They are just stumping as usual. The only difference is that they have a national audience to woo one way or the other. The clips I saw were actually humorous to me! In short, neither of them did anything positive or negative to sway polls. Typical of a veep debate. It just primes us for Tuesday's showdown between Barack and Mitt. So here are my questions to you all....

Was there a clear winner?

Would Ryan or Biden make a good Prez if he had to step in?

Does either candidate help undecided voters decide?
