Seems to me, unless the debate formats are changed such to something not dissimilar to what
@Chad was suggesting, it does not really matter what the moderator does. A debate would include an actual discussion of the issues, rather than a guided recitation of stump speeches and subsquent mud wrestling, that then he had trouble controlling. It really concerns me that apparently the public does not know how to think. Or that the sponsors or organizers of these "debates" believe so. The last debate is on my birthday. I am hoping to find a way not to waste my birthday watching it. But, . . . the train wreck! Really truly hideous.
