Barack Obama's response to Tim Russert's questioning and Hillary Clinton's barbs on Farrakhan may suffice for those who don't listen closely, but the repudiation of only his anti-Semitic views struck many as lawyerly. See law professor Ann Althouse's deconstruction. The generally pro-Obama JTA website collects commentary.
Compare how the late William Buckley acted toward Joe Sobran for antisemitism -- he fired him from National Review. What about Pastor Wright? I have not seen a critical word about him from Obama in 20 years. Just a dis-invitation from the announcement of his candidacy and an apparent wish that nobody notice how close Obama has been to him.
