The moderators had a few good moments near the beginning, like when that one lady really put pressure on Carson to explain how his tax plan would actually function, but once Cruz called them out and got applause for it, they got totally sheepish and let everything get totally out of control. And most of the questions were too tailored toward trying to goad soundbites and infighting out of the candidates, rather than actually getting them to say anything of substance (or, alternatively, showing their positions to be insubstantial).
As a debate, it was absolutely terrible, but it was kind of wonderful to watch in a reality television kind of way. They were absolutely laying in on each other at times. It really made one appreciate just what Trump has done to the race, as they were ALL trying to out-Trump each other.
