Early voting is an option in many places too!

Voting early is usually less stressful, and you can schedule it easier (because election day isn't a national holiday for some reason). Look up the dates early voting is running in your county, read up on what polling stations you can vote early at, and make a plan!

As far as changing minds though... yeah, everyone is pretty much locked in at this point. I just hope people in the US cast a ballot even if they don't plan on voting for the president. There are so many downballot positions for local offices that one's vote can have a huge impact on.

I think if people are resigned to not pick between outright vs lite genocide (understandably), the best thing they can do is research their local elections, make a list on who they plan on choosing for each office, and make the decision on the president (including the choice to do a write-in or leave it blank) when they get to the ballot box.
