Of course, then the Reichstag caught fire, and that was about it for Weimar democracy. But up until that point, his political success came off the back of genuine popularity at the ballot box. He only managed to became Chancellor because enough people voted for him.
It was a choice: Socialists, Nazis or communist, and as always "Plutot Hitler que le Front Populaire", the extreme center choose fascism. The more thing changes, the more they stay the same.
That's why both of them managed to get their message out to so many people. That might then convert to votes, but are the voters that believed the propaganda at fault as much as the people who paid for it, those who created it, and those that spread it?
Nevertheless, it's propaganda that many Americans have swallowed, and those people then go on to put Republicans in power year after year. I can't fault Democrats for their bitterness towards Republican voters.
If you’re aware of any more accurate modelling, I’d be super interested though!
In fact, the Nazi party electoral results were down from the previous election. Both the socialist and communist party were up however, and so the men in power chose Hitler to change that. All of those were killed or politically neutered within 6 months, and honestly, they made their bed.
