The only issue I have is the last part. Don't wait four years to talk about whatever the issues are, you have representatives even in the outgoing administration and congress right now to contact. By all means vote for the right people to make sure you can still do that after the election without fear of retaliation, but don't vote and then complain fours years later nothing was done if you haven't reached out during that time frame.
It really is surprisingly effective. So few people actually contact their legislators.
I set up a harassment campaign and got a few hundred people to contact a state legislator whose committee was holding up legalizing weed in my state and a few months later it was legalized. Agitate. Make a difference. Protesting doesn't do shit, get all the people there to call their representatives and senate members - especially for state and local stuff, and you might actually get something changed. Or even better, send a letter.
Yeah, this year the German government passed the law for decriminalization of weed, and it was almost blocked by our Federal Council if it weren't for thousands of community members harassing them on social media and via Fax (yes, Telefax is still used by our government 🤦)
