This is what I think would be most probable too. It's still too socially stigmatized to outright say something that effectively just means "I'm a Nazi," so they'd have to play it off as some kind of joke.
I do, however, think a lot of them would suddenly, for no reason in particular, begin saying things like "Well, Hitler was a bad guy, but he did have some good ideas..." while going on to describe some of the worst ideas known to man.
They all like their Frauhauspanzers and Bro Dozers. I think when the diesel douchbags on YouTube started breaking the deploreans (incidentally because the subframes are aluminum), that musk finally realized that even a car as militantly threatening as the cybertruck wouldn’t sway conservatives. I think he might be looking to rug pull TSLA and try to shoot the moon on debt.
