This one was more debate-like, though often the candidates spoke right past each other.
This was an exchange, which illustrates most of the debate:
McCain: "Obama is going to government mandate health care and fine Joe the Plumber"
Obama: "Actually, Joe's fine would be 0 because he's running a small business," followed by a very, very careful explanation of his system which doesn't mandate a damn thing.
McCain: "So, as you can see, Obama is going to government mandate health care, and fine Joe the Plumber."
It's like they were each talking to a wall. That example goes one way, but there were just as many going the other.
