Gingrich's "Anti-Semitic Diatribe"

Richard Silverstein didn't like the sound of Newt Gingrich's South Carolina victory speech:

We are going to argue American exceptionalism, the American Declaration of Independence, the American Constitution, the American federalist papers; the founding fathers of America are the source from which we draw our understanding of America. [Obama] draws his from Saul Alinsky, radical left-wingers and people who don’t like the classical America.

Silverstein:

Alinsky’s Rules for Radicals is replete with multiple references to the Founding Fathers and American constitution as the embodiments of liberty and democracy. But note how he sets up Alinsky as a radical who is alien to America. The final nail in the coffin is his reference to “classical America.” Who or what is classical America? It is of course white Christian America, everything that Saul Alinsky and many of you out there reading this are not. This is a classic anti-Semitic diatribe gussied up in Tea Party rhetoric.
