I completely agree about McClellan looking weak... but I've heard that he has a history with Bush and that he was awarded this job. No one can say that they can't find anyone better...
He drives the shrieking hyenas in the White House press corps nuckin' futz with his calm demeanor. Thus, causing them to foam at the mouth and shriek even louder, asking ever more stupid questions, making themselves look even more ridiculous.
Yes, I still miss Ari - he was wonderful, and had a sense of humor that Scott unfortunately does not possess, but Scott has definitely "won his wings" IMHO.
Perhaps ... Dede Miers, Clinton's first press secretary (who was obviously in way over her head) had a history with the Clintonistas and they didn't waste any time getting rid of her. Although, as I recall, it was made to appear it was her idea to leave.
