In his first campaign it was said that the only book he kept and actually read was the English translation of Hitlers speeches. He has never really shied away from his adoration of the mustache man.

Videos talking about building a unified Reich, talk of immigrants polluting the blood of the nation, a lot of talk from his orbit about cultural Marxism, all the shared enemies (other than Israel, who are now the genocidal fascist ethnostate he aspires to), Nazis consistently turning out to support him... It's straightforwardly Nazi bullshit. At least Hitler did prison time for the beer hall putsch - Jan 6? Fine, apparently.
