She's doing the same think with Lamont...putting the money in the pot for their re-election but staying as the "tough" (pretend) Commander in Chief. She's getting splinters from straddling the fence.
You've got a point, she has definitely been straddling the fence and moreso with the polls of the last few months. I don't remember Lamont coming out and criticizing her like Murtha is though. Of course it could be a way to ease her into a complete change on her stance I guess.
