ROGER KIMBALL: In Democratic circles, anti-Semitism is becoming normal. “As people scramble to explain the sudden resurgence of socialism not only on America’s college campuses but also in the corridors of political power, it is worth noting the concomitant resurgence of anti-Semitism in those redoubts. The coincidence is not, as the Marxists like to say, an accident. The truth is that unfettered socialism, though based primarily on a demand for the abolition of private property, always comes riding on a current of anti-Semitism.”
