I watched because I was polled by the Zogby organization prior to the show about my feelings on the show and its two characters. It was clear to me that the poll was a 'focus group' to help design the parameters for the show.
Then as I watched the credits, I found this 'live' show was actually scripted. By whom? Lawrence O'Donnell, the ultra-lib screamer. The show may have been 'live' but the script was DOA as far as I was concerned.
The problem is that some folks may have been fooled by the fiction that 'live' meant that the participants were in a real debate.
No surprise that the 'sound bite' lines and applause lines were pro-Santos (liberal) and Vinick (conservative)had a few that made him look weird.
Show was scripted. The shows producers said it was earlier.
