I watched part of this, and I came away with a very favorable impression of Carroll's performance. That said, I have no real idea how to score these things as wins or losses, especially when I have such a heavy prior bias. I will say, though, that Jeffery Jay Lowder, an atheist who follows these debates closely and is usually very critical of Craig's oppponents, said that Carroll dominated the debate and did as well as anybody who has ever debated Craig.
