This is good, and I'm piggybacking so I can add on:
Get a passport, make friends in another country.
Vote to slow them down, yell at anyone who tries to say that it's better to not vote or that Trump would be better for Palestinians.
If you want to engage in electoral reform, you need to start years in advance.
If you live in Texas: Vote for Biden and encourage GOP voters to not vote for Trump. If you're in a place with lots of GOP weirdos, try publicly and loudly watch his rallies at 1.5x speed; I've heard it breaks the spell b/c his cadence gets disrupted. If Texas goes blue, Biden wins and all the DNC voters suddenly know they can win, making it immediately more likely.
If all else fails, remember someone might [Comment Cannot Legally Be Finished], which would solve multiple problems.
