Jews were once a major, perhaps THE major, component of the American left-wing and what is now called "liberalism". But now Al Qaeda, Hamas, Hezbollah and other radical Islamic groups have become the latest radical chic. Thanks in part to a huge infusion of Saudi Wahhabi money into the Democratic party and leftist causes, the "liberals" have become strongly anti-Jewish.
We once heard expressions like "Hitler stopped too soon" from right-wing hate groups like the KKK; now we hear it more and more often from the left. Left wing blogs and web sites blame the Jews for 9/11 and for all the problems in the Middle East. "We must end the **** influence in American politics," screamed one leftist web site poster, and assured his readers that Obama would do that. Another "liberal" said that Obama would order the "extermination of the Jew scum" within minutes of his inaugural, along with executing Bush, Cheney and every military officer; banning all religions but Islam; imposing Sharia on the country; etc.
A disturbing aspect of such nonsense is that the loonies really seem to have believed it. Since Obama has not done those things (and probably won't), those hate-filled "liberals" will be out to get him, and perhaps not politically.
