Hindenburg was the centrist incumbent, he didn't go around publicly calling for genocide like Hitler did, but then he placed Hitler and some other Nazis in key leadership positions because he wanted to ally with his party, and two years later Hitler seized power after his death.
Biden has never called for a genocide, yet he has been actively funding one for 8 months while all the progressives in his cabinet are quitting. He seems unbothered by an election loss to Trump so long as the Pentagon's foreign policy succeeds. I wouldn't even be surprised if he dies in the next 2 years considering his health and stress of being president.
People don't understand that Trump is a symptom and not a cause of the system. Even if he loses this election or dies or is disqualified, another equally or even more insane Republican will take his place. Meanwhile Democrats have refused to actually pass sizable progressive policies for 30-40 years. Biden only got to make his $15 minimum wage promise for only federal employees via an executive order because the party fell apart in congress with an actual bill. This will only lead to more republican voters.
Part of the issue is two party politics, but another part is the DNC refusing to combat fascism because surpsise surpise their candidates are funded by huge megacorp lobbyists who want to protect their corporate interests. Biden winning will not fix the problem, and 4 years down the line we will be faced with the exact same scenario.
