I like this guy and substantively I agree with him on this, but I do think the idea that anything of any consequence hangs on the question of whether he, Ezra Klein, liberal blogger, formally "endorses" Harriet Miers, as opposed to just saying that he's pleased about it (which he says he is) is sort of hilarious. It's as if he's imagining a news story saying "Miers Gets Klein Nod" or whatever.
