I dont think there is a single Republican convention that has press present that would unironically play Hitler speeches. Behind closed doors, in the boys clubs, almost certainly. But they are still playing with dog whistles most of the time and pushing parallel policies mostly under the guise of sensibility, not actual out and out racism (normally). Many of their electorate are fully masks off more. The politicians aren't so stupid as to go fully mask off while they rely on independents for elections.
