Read E. L. Doctorow's Worlds Fair.
In it (a pretty good book, too), ALD fictionalizes an America neutral in WWII, with Lindbergh's America Firsters running the country. In the book he spells out his "Jewish" fear and the "danger" of "Right Wing" Christians, "Conservative" political thought, Capitalism, and "latent American Anti-Semitism."
Good read. Sort of a political "Portnoy's Complaint."
