I think you hit it on the head. They said Romney had been invited and was the only one who had declined. I don't know how much was because they're pissed that he declined after they've campaigned so hard for him or how much is because they finally realized he's not gaining any new traction and they fear Cain as you said. Either way okay by me.
FNS gave him one long campaign ad.
RINO run Fox News is still Mitt country but if he falls they are only too willing to move next door to Perryland.
