Rumsfeld redux

Maureen Dowd asks how this dangerous chucklehead kept his job. I think it's pretty clear: he's the sacrificial lamb being fattened as we watch. With the prisoner abuse scandal clearly set to burst through the dike at multiple points, they need a fall guy, and who better than Rummy? Everyone already hates him anyway. Getting him out into the field to insult the troops will just make his downfall all the more satisfying to those not interested in ultimate causes. If Rummy is hated enough, no one will look higher than Rummy, is what I assume Rove is thinking.
