The 1920s and 1930s had a surprising amount of pro-Nazi sentiment. Remember, USA didn't learn about the Holocaust until 1943 or something (long after it started, and even then only as a rumor in niche papers). The proof of the Holocaust didn't hit until 1945 or later.
Meanwhile, America First Committee and German-American Bund were pushing pro-Nazi sentiments.
If we expand the political groups to the next degree of freedom (ex: Christian Front marched with German-American Bund. I don't know if you could call Christian Front a Nazi-organization, but they were 100% comfortable with marching with the literal Nazi groups), there were plenty of political groups who were "directly a Nazi supporter" and/or "were hosting political rallies and inviting the Nazis".
