This is general advice regardless of party.
Look at your your town/city govt and keep an eye on meetings (a lot are streamed now post Covid). Know the people in office and what they are for/against. Focus on actions more than words. Vote for people you believe in and keep in contact with them. They can be surprisingly approachable.
Act similarly at the state level. Know and pay attention to the justices, senators and representatives. Reach out on issues you find important.
Being informed on govt and politicians doesn’t happen through ads and comment sections, and it doesn’t stop when elections are over. Do what you can where you can for what you believe in.
And maybe just maybe it will result in a solid Presidential candidate
