This isn't Blumenthal's first flirtation with hate-speech. As I wrote here, Blumenthal gave several interviews earlier this year in which he called U.S. politicians who support Israel "quislings", thus equating them with the puppet leaders installed by the Nazis in the countries they occupied.
Blumenthal may imagine himself to be making trenchant, deliberate provocations. I suppose Ann Coulter imagines the same thing.
