If I was betting, I would bet the Romney campaign was behind the taking down of Cain. I would also bet that they were behind the attacks on Sarah Palin.
The Romney campaign through his people he can’t ‘control,’ has been the most vicious and the most negative and this has not been returned in kind, so far.
I think Newt Gingrich is now annoyed enough to do it.
As far as Cain and Palin are concerned, Romney did not take them out. Palin had been vilified for years and withstood it. I don’t know why she decided not to run but it wasn’t because of Romney.
As far as Cain goes... he took himself out and needs to go away and forget his 9-9-9 bus tour.
