Palin is NOT a part of the establishment Republican Party therefore all establishment Republicans MUST denigrate her and her political skills. She is too liable to break off on her own path and that is not permitted.
The establishment Dems and Reps already have chosen a path for America and that is failure. Then they will proceed to building the New World Order as approved by the United Nations.
It's an important observation--because you appear to be suffering from "confirmation bias."
