IIRC correctly the Progressive Party controlled several states in the 1930s, 1940s etc without making much of a dent at national level. I imagine the same thing would happen
Using the terms "fascist" and "communist" probably obscures the argument - after all, if its the 1950s I doubt there's a chance in Hell either would get elected. But if its BEFORE 1940, then a different dynamic, and if its say after 1991 then another.
The problem IMHO is that for the scenario to work, the political dynamics of that period in OTL have to be significantly warped, and this would thereupon change the reactions of other political parties etc
Hmmm, not as clear as what I meant to be !
