The first thing you need to know is that if Trump gets elected, there is no discernible point between whether he “goes dictator” or not. People just use power and whether they’re a dictator is a subjective exercise for historians.
Second: if Trump gets elected, everyone should actually be doing the same things they do if Harris gets elected, which are also the same things we should all have been doing under Biden, Trump, Obama, etc: which is building a base of local power to stand up for the most threatened among us and push back against authoritarian state power.
In practice, this means getting to know your neighbors. Knowing who serves as your mayor and city council and county council, and police chief, and local prosecutor. Then you need to organize with your local community to build political power to support democracy and oppose authoritarian power. And if you and the folks in the next town do this, you form a bloc of political will to do the same thing at the state level, and eventually the federal level.
This work still needs done if Harris wins. She is a better person than Trump, but the larger system both would command is a loaded gun. We cannot simply keep trying to keep the gun in the hands of the lesser of two evils, we need to remove the bullets. That means things like public financing of elections and ranked choice voting. It’s not as dramatic as shooting politicians you don’t like, but unfortunately, in the real world this is how dismantling fascism actually works.
Well tbf I don’t disagree with that, but good luck with it (and especially in time for the next presidency to end, which is about 4y).
Tbh it seems more likely to me that either one would say “know what? I’m king/queen now” and get domed by someone who works “for” them who says “nope” than all the country comes together and builds support networks, but ya can’t place all your eggs in one basket.
