Democrats got a reminder of just what the far left wing of their party is thinking these days when a debate among contenders for their party’s nomination in the race to replace retiring Senator Joe Lieberman was overshadowed by vicious anti-Israel rhetoric on the part of one of the candidates. Candidate Lee Whitnum called frontrunner Rep. Chris Murphy a “whore” because of his support for Israel. She also referred to another candidate as “ignorant” during the course of the debate that was televised by the local NBC affiliate.

Whitnum, the sole focus of whose campaign is hatred of Israel, is a marginal player at best in a Democratic race that centers on the competition between Murphy and former Connecticut Secretary of State Susan Bysiewicz. But her ability to get on the stage and spout bile against the Jewish state and its supporters is something of a victory for the Occupy AIPAC crowd and a warning to both Democrats and Republicans about their obligation to denounce anti-Semitic agitators who seek to worm their way into the mainstream.

Whitnum’s candidacy is more or less the embodiment of the Walt- Mearsheimer conspiracy theories. She is obsessed with AIPAC and Zionism and spends a great deal of space on her campaign website trying unsuccessfully to assert that she is not an anti-Semite. But at least she comes by her bias honestly. According to her biography, her father was a British military officer who served in Palestine during the 1940s when the U.K. was preventing Jews from immigrating to their homeland and assisting Arabs in their efforts to prevent Israel’s birth.

Murphy rightly denounced Whitnum’s comments saying, “This is in our national security interest, ultimately in the interest of U.S. taxpayers to have a strong relationship with Israel and I think it is worth saying on this stage that a lot of her comments have been out of bounds and over the line.” He also said he was reconsidering his support for allowing marginal candidates access to the debates.

Support for Israel in the United States is bipartisan and encompasses a broad coalition of members of both parties including liberals and conservatives. But the virus of hate is alive and well on the margins, especially the far left where, as the Occupy Wall Street protests proved, Jew-hatred seems not far below the surface.
