As for how the candidate I'm watching, Joe Biden, is doing at the two-hour mark, I ... don't know for sure? I don't know how anyone has done, really. Klobuchar has been good, I guess? It's been a weird debate. As I said before, I think it's good for Biden that he's had some presence tonight instead of fading into the background. I also thought his hit on Sanders on guns was potentially effective. But he hasn't always been smooth, delivery wise, and his "expectations lowering" answer was weird. So it's sort of a mixed bag.
