I do in fact have a scenario in mind for how a fascist and nazi-sympathizer (which, and I want this to be clear, Woodrow Wilson wasn't IMO) of sorts could get into the white house, but, as I said, the forum for that scenario is not the post-1900 one. And if for any reason you really can't see why, let it be enough for me to say that it'd require transposing and adapting to the 40's events so recent, that it'd be impossible to avoid a staff intervention
Now, if your reply is going to be that recent events can never to any extent be possibly adapted to an allohistorical, previous context, I'll tell you right now that I firmly disagree
