this 100-mile border rule has been on the books for a while long before Trump. and people have been saying for a while that it could lead to fascist actions against individuals. if you give an institution the power to silence its critics it will use it eventually regardless of how 'just' it claims to be. it's not really a single-party-does-it-wrong issue, at least not since neoliberals took over the left-wing party
which is to say - you sure can vote. but if you really want to do something, there's plenty of local hacktivist groups around doing things like logging ALPRs to maps, attending townhalls to yell at pro-surveillance councilmembers and the like
my experience with those groups is that anybody who's remotely tech savvy and/or a spreadsheet whiz is a godsend. I was one of two people in a 30+ person group who knew how to, for eg, set up breakout rooms, keep virtual attendees engaged, automate email sends, etc. if there's one thing movement organizers are generally bad at it's knowing how to use the technical tools to actually stay organized
you can also be the person who gets them to move off of Google and onto at-least Proton (though ideally something like Cryptpad). anybody with a halfway-competent understanding of OpSec could've prevented a lot of the things that led to the doxxing of individuals and people leaving the movement due to harassment
