A big difference...in advancing the RINO agenda of progressivism, globalism, and fascism over a libertarian conservative, Tea Party, America First agenda!
Or, are you ignorant of some realities in the U.S. Senate?
RINOs will always screw you in the end!
Just say HELL NO to Fiorina, Whitman, Romney, McCain, et al.!
If McCain goes, I hope Arizona puts Republican J.D. Hayworth in his place.
