I don't want to resurrect an old debate but I guess I just want to chime in with my two cents. I really, really think making Huey Long the only NatPop option for America kind of glosses over just how much more radical, race and Christianity based, and overall just different the at-large far-right movement in the US was compared to him. People like Coughlin and L. K. Smith were at some point tagging along to Long but their brand of nationalism was a lot more outwardly reactionary. Christian Nationalism was the fundamental value that these people held instead of Long's progressive-tinted populist nationalism, and while I can see how their views could change if Long is popular and gets power I do not see how or why these people would abandon their racist and fundamentalist positions and stop trying to push these policies.
I guess one way to tackle this would be to simply add one more path where Long loses control of his movement, leaving the Longists with two AuthDem, one PatAut and two NatPop paths. Long would be the more idiosyncratic, unconventional NatPop and somebody like Gerald L. K. Smith could be a more usual fascist option. Now I get why people wouldn't want to represent essentially Nazis in the mod but I feel like that whitewashes the fact that if a far-right movement took power in the mod's timeline in America, they would be very racially and religiously motivated.
