I wouldn't say the Democrats Song since the Democrats represent the Left and Hitler represented the Right and the Nazi's here in the US had no use for the Democrats & the FDR administration policies against Hitler.Democrat Party song:
German American Bund
The German American Bund or German American Federation (German: Amerikadeutscher Bund, also Amerikadeutscher Volksbund) was an American Nazi organization established in the 1930s. Its main goal was to promote a favorable view of Nazi Germany.
The Bund held rallies with Nazi insignia and procedures such as the Hitler salute, and attacked the administration of President Franklin D. Roosevelt, Jewish groups, Communism, "Moscow-directed" trade unions and the American boycotts of German goods.
