I haven't seen this anywhere yet but I think it is possible that the lefty calls for Rummy to resign kept the POTUS from kicking him to the curb early.
He is after all a child that likes to give the impression that he does things on his own terms. The calls for resignation built to such a tenor that even Loserman echoed it and eventually a statement of faith in Rummy was issued.
It wouldn't be unheard of for the Dem leadership to have gotten wind that Rummy was to see bus rubber. They certainly knew calling for his resignation was value added, but did they figure the child POTUS would refuse if they demanded the resignation? Was there a concerted effort?
