He fundamentally helped reshape American liberalism as a movement that wants to use government intervention as a means to uplift the lower classes - while before American liberalism was mostly anti-government, believing that its intervention would only mean subsidies and favors to the wankers bankers and the ruling classes. And that is his most important legacy.
But more specifically:
He was a populist, anti-imperialist hero (good)
He attacked snob and wealthy city-dwellers (good to an extent)
He supported women's suffrage (good)
He accepted Jim Crow laws (very very bad)
He supported Prohibition (I'm inclined to say good)*
He was a full-fledged creationist (bad)**
So I voted narrowly for "FF".
*I will be roasted for this... guess I should befriend ExtremeRepublican
**Although most evolutionists at the time were full-fledged eugenicists...
By the way, H. L. Mencken, the journalist who popularized the Scopes trial and attacked WJB in his articles about it, was a f***ing misanthropic resentful man who wrote scathing articles on pretty much everything that came to his mind. He loved Nietzsche, and indeed had the same f***ing "men are ignorant and stupid monkeys fooled by religion and democracy" attitude of Nietzsche, coupled with a big "racist towards everyone" one too.
Nah, Prohibition was hardly a terrible idea on paper, I agree with that.
I reckon I'd support Hoover over Smith for precisely those reasons, since they were mostly identical otherwise.
