Joe Klein, who loves the guy:

I suppose he will have to be sacked now. He is not irreplaceable. There are more than a few fine generals in the Army, including Lt. General David Rodriguez, a McChrystal deputy with vast experience in Afghanistan. But it is a terrible setback, a diversion from the business hand at a crucial moment in the conflict. And it is a real tragedy, because Stanley McChrystal is precisely the sort of man who should be leading American troops in battle.

Fallows:

If the facts are as they appear -- McChrystal and his associates freely mocking their commander in chief and his possible successor (ie, Biden) and the relevant State Department officials (Holbrooke and Eikenberry) -- with no contention that the quotes were invented or misconstrued, then Obama owes it to past and future presidents to draw the line and say: this is not tolerable. You must go. McChrystal's team was inexplicably reckless in talking before a reporter this way, but that's a separate question. The fact is -- or appears to be -- that they did it.

Ackerman:

Yesterday, Gates passed over Gen. James Mattis for Marine Corps commandant. If Obama wants to cashier McChrystal but not overhaul the entire strategy, Mattis is an option. Whether he’d do it is another thing, since he’s the outgoing commander of U.S. Joint Forces Command, so taking over ISAF will technically be a step down. But Mattis will otherwise retire from the Marines, so maybe he wouldn’t see it that way.
