In a recent interview with Brian Williams of NBC, Caribou Barbie (with John McCain watching over her) told Willliams that Bill Ayers is unquestionably a terrorist because he tried to destroy the U.S. Capitol and the Pentagon. Williams asked Barbie if abortion clinic bombers would be considered terrorists too - in Barbie's mind, well, not so much...
WILLIAMS: Is an abortion clinic bomber a terrorist, under this definition, governor?
PALIN: (Sigh). There's no question that Bill Ayers via his own admittance was one who sought to destroy our U.S. Capitol and our Pentagon. That is a domestic terrorist. There's no question there. Now, others who would want to engage in harming innocent Americans or facilities that uh, it would be unacceptable. I don't know if you're going to use the word terrorist there.
The icing on the cake is that McCain has voted time and again against protecting innocent citizens from domestic terrorists attacking abortion clinics.
