When a baseball manager gets thrown out of a game by the umpire, he has to leave the field of play, and the managing duties passes to one of the coaches. Presumably.
What actually happens is the manager skulks to the clubhouse and continues managing by sending the clubhouse attendant to the dugout, who relays instructions to the coach, who then implements the will of the manager.
The point here -- even if Rove is forced to leave his White House job, either because of successful prosecution or political untenability, what makes us think he won't continue running the White House political machine? He is just as capable of spinning his webs from outside the White House as he is from inside. He'll just keep sending instructions from the clubhouse, even if the clubhouse is situated in a Club Fed Prison Resort.
Rove is an inevitable force until Bush leaves the presidency and having him lose his job will not matter one whit. There is a lot to be gained from this situation for those of us who oppose this White House by keeping this prosecution alive and on the front page, but the elimination of Karl Rove as a political player is not in the cards.
