Pure McCarthyism

Michael Goldfarb, McCain spokesman, accuses Barack Obama of hanging around with anti-Semites - plural - on CNN. Asked to name one other anti-Semite other than his allegation about Rashid Khalidi, he can't. He won't. But he leaves it hanging, refusing to disown or retract the charge. This is pure McCarthyism. And it is the rotten core of McCain.
