If you follow one information source, let it be this one

I recommend starting with this article:
https://www.ifyoucankeepit.org/p/reverse-engineering-autocracy

Then review and vet the group that runs it:
https://protectdemocracy.org/about/

Then look at this informative presentation:
https://protectdemocracy.org/wp-content/uploads/2025/01/How-You-Can-Protect-Democracy.pdf

The above presentation is a 22 page slide describing 29 "concrete actions" that each  individual can contribute to protecting democracy - here is their description of the presentation:

"In this guide are 29 concrete actions you can start taking right away. These actions offer not only knowledge, relief, and power, but also joy, fun, and community. And, of course, you donʼt have to do all of them to make an impact. Challenge yourself (and others!) to complete as many as you can in the coming year. Some take less than 30 seconds, some may take months, and some will never truly be complete. Protecting democracy is a generational struggle. Now letʼs get started"
