Read Chris Hayes on the psychology of the press corps here. I'd add that it's a bit astonishing to watch the real-time narrative construction that went on at last night's debate. I must have heard the term "meltdown" in reference to Hillary 65 times. And I talked to reporters who would literally say, "I thought she did okay, but I just misjudged it" -- the aggregate conclusion of the corps became some sort of objective, or at least agreed-upon, truth that the outliers measured themselves against. Very, very odd. Particularly because the part that much of the press liked least -- her heated recitation of the programs she's fought for -- came off, to me, as one of her best moments. Meanwhile, there is, on some level, an acknowledgment of the weirdness of all this. I was at a bar talking to some leftier members of the press last night when a reporter wandered up and asked if "we were discussing Hillary's meltdown, or talking about real things?" Most of the folks I talked to happily admitted how unbelievably awful and surreal the spin room is, but everyone was in there. At one point, I asked an older reporter why everyone was assembed together for this debate, and he turned to me and said, "there's no good reason. Reporters are creatures of habit, and all this is now habit."
