I'm no expert on debates, but I was paying significantly more attention to your message simply because he was being so rude and obstinate.

For your part, you did extremely well to not even acknowledge that he was trying to interrupt you at all.

But of course, I walked in with a bias on the subject.

Echoing cbo a little bit, I agree that you did well dealing with the NBC GC's interruptions - you were steady even when he was trying to jump in, and as long you have a reasonably effective moderator (like Chris in this segment), you will be heard. Creating that contrast is important - rather than letting it escalate on both sides, you get points for sincerity over obstinacy.
