An American Fascist seeking power would not proclaim that he is a
fascist. Fascism always camouflages its plans and purposes. ... Any
fascist attempt made to gain power in America would not use the exact
Hitler pattern. It would work under the guise of "super-patriotism" and
"super-Americanism". Fascist leaders are neither stupid nor naive.
They know that they must hand out a line that "sells". Huey Long is
said to have remarked that if Fascism came to America it would be on a
program of "Americanism".
