Marc Ambinder makes essential points in back-to-back posts:
What you're really seeing here is thoroughly desperate campaign spinning out of control in its final weeks -- soon to be days.
Also, credit where credit is due: Yesterday, The Nation's Ari Melber, kossack dawnt, and Politico's Ben Smith all saw through the Penn smokescreen.
Update: Ben notes that Clinton folks are still saying that the "central point here is that he's out, not that he's in." Color me skeptical.
