Unbelievably, Gray Davis is here. He acts as a sort of dementor upon the gathering of otherwise happy delegates and media types. Some folks survive political smash-ups. There was a big party for George McGovern last night, for example, and all the Dems love him. He lost with --in their eyes-- honor. But some, like Gray, had such bad exits that they ought to exile themselves for the good of the general mood.
