I agree, Gwen was better than Jim Lehrer, but still not as objective as a true moderator should be. The first thing she did that bugged me was letting the Silky Pony "rebut" before she ever granted him his 30 seconds. He just started talking, and she should have said, "Wait a minute. I didn't say you could respond." Of course, she would have been voted off the MSM island for such a faux pas had she actually stuck to the rules to the Hairdo's detriment.
The one that got me was when Edwards mentioned John Kerry when he wasn't supposed to, and then was allowed to shrug it off, and then used his name again with a 'well, I've done it before so I can do it again.' What good are rules if they're not enforced?
