Fascists want to win because it means there will be less resistence from liberals, not because they will abide by the law. That's a pretty important distinction that I don't think liberals can integrate right now.

A successful coup is indistinguishable from a legal election, which is why they create as much chaos as possible and sew distrust before elections.

I'm not saying voting is completely useless but I am saying that you are deluded if you think voting will save you. It might not even buy you more time. Organize now. Figure out how you're going to eat while you're fighting. Download army manuals and start reading them. Start talking to other people about what to do when Trump takes power (acknowledging that he will claim power reguarless if he wins or loses the election).

A coup is less likely to be successful if you promise to revolt no matter how a fascist takes power. They rely on tricking enough people in to cooperating. If enough people will riot, some of the ghouls who back the fascist will back off and you lower their chances of success.

You don't have time. Sure, vote anyway because it's a low effort thing that might buy you time. It's basically a free lottery ticket. You probably aren't going to win, but it will be really great if you do and it's super low effort. But you wouldn't take out a loan assuming that ticket will pay off. Act like voting won't actually buy you time, because it probably won't.

At most it's gonna pull some of the people from it before it drives of the cliff.

Vote for shit burgers or don't. The time to build a movement was 4 years ago before liberals decided to go back to brunch. The thing is that fascism requires the complicity of liberals. A very small group of people could beat the driver to death, take the keys, and park the bus. Liberals will work with fascists to resist those people because they think they'll get the keys back later and get ice cream. Liberals can't accept that there is no ice cream and there never was.
