What Are we Suppose to Get Out of Debates?

This video allows us to hear what America people thought of this Obama/McCain debate. The range of opinions and ideas about who came out stronger in the debate gives us a sense of what a real Presidential debate is suppose to do: make us think one candidate is better than the other, as oppose to the Cain/Gingrich debate which wanted to make both candidates look good. One caller hit it on the head saying it was "a lot of finger pointing," something that often comes out of Presidential debates.
