The establishment republicans (ER’s) have been brain washed from decades of democrat dominance in congress and decades of left-wing media attacks. These ER’s will do everything to curry favor with the media by attacking other republicans. Prime example: Maverick McCain. But attacking democrats is a no-no because then the media will not love them. Anyone recall McCain attacking any prominent democrat?
Yes, McCain acted like a vicious attack dog during the 2008 Presidential election. He was always challenging Obama.
