The debate has three moderators. Hugh Hewitt is brilliant and I would choose him to moderate every debate if I could. Jake Tapper is an excellent, fair reporter (right up there with Ed Henry). I don't know who the third moderator is, but I'm guessing she's a more typical MSM liberal. Still, 2 out of 3 is not bad at all.
The problem will not be moderators but the format. Putting 11 candidates on the same stage is stupid. CNN has tried to compensate by making the debate nearly three hours long, but that doesn't change the fact that you can't engage in a meaningful debate among 11 friggin' people. The canididates will not be afforded the time to all address the same issues, let alone the same questions, which doesn't allow for meaningful comparison. They could have broken the candidates into 3 randomly selected pools of 4 candidates and given them each an hour and gotten a far better result.
