Their response to the far right fooferaw was simply to go silent, to keep Grenell off-stage and mute, and to wait till the storm passed. But the storm was not likely to pass if no one in the Romney camp was prepared to back Grenell up. Hence his dilemma. The obvious solution was simply to get Grenell out there doling out the neocon red meat - which would have immediately changed the subject and helped dispel base skepticism. Instead the terrified Romneyites shut him up without any actual plan for when he might subsequently be able to do his job. To my mind, it's a mark of his integrity that he decided to quit rather than be put in this absurd situation. And it's a mark of Romney's fundamental weakness within his own party that he could not back his spokesman against the Bryan Fischers and Matthew Francks.
It's a fascinating post, and it hints at how scared of their own party the Romney campaign really is. I suggest you go read the whole thing.
