It's interesting to sit back and watch this debate as a disinterested observer. I agree that CNN was more tolerable than the others. It was not unbiased, The others went down hill from there, although I can't say for sure about Fox, I haven't watched it in a decade or so.
For those that wonder about my "disinterested" status - I'm a Libertarian. I know, most of you think that means I'm a Republican in disguise. All my Republican friends think we're Democrats in disguise.
