Trump is definitely unique in one respect, in that I don't think anyone else has the personality to keep all the disparate right-wing factions more or less goose-stepping together. This coalition is beginning to break up now, the infighting has started, but that it has held together for so long is solely down to Trump.
Someone like Vance could not pull this off ever, and when he shortly becomes president, infighting among the factions will tear the MAGA movement apart. Vance is Theil's lapdog and the techbro agenda does not chime with the nativists, the fundamentalists, America first, etc However, the brick may have gone too far down the authoritarian path to save it at this point. Most historians agree that no country has come back from this point without a violent upheaval. Either way, Trump has definitely destroyed America's standing the world, such as it was, and that will not be fixed in the short term.
