They say your time is much better spent guaranteeing people who already will vote blue show up to polls than trying to change the opinion of people who will vote red.
So that looks like asking people "do you have a plan to vote?" And perhaps in a less nosy phrasing: "When will you vote?" "How will you get there?"
People verbalizing a plan makes them more likely to follow through.
There are many places you can sign up to go canvassing, which is great. I would suggest in addition to and maybe before that, make a list of everyone you know and would feel comfortable talking to, and talk to them about voting. You will get much more mileage from existing relationships. (It's like how sales differentiates a warm lead and a cold lead)
Once you've exhausted that list then every little bit still helps. I do think high density events like farmers markets, community gatherings, concerts, games, etc have better rate of contact than door to door.
I realize I just essentially said to tell people to vote while you were asking for something more. I wanted to share that because some people think that posting "vote" is the same as having a conversation about voting. Posting is not nearly as effective.
Another thing that might help is directly asking elected officials to intervene. Staffers for politicians keep a tally of calls and letters they receive for/against a given issue. So while your words may not move an elected, you and some friends can get them to act on an issue. If you have a group you can also request a meeting to discuss your issue which is even more effective. Politicians take notice of organized groups of constituents since that's a block of votes for/against them and possible a group knocking doors for/against them.
The trouble is I don't know what the ask is. There should be a specific action you're demanding: "introduce this bill" "cosponsor this bill" "vote for/against this bill". And it has to be something they're able to do. I don't know what that thing would be.
Pack the supreme court (but there's not time for that or majority in the house).
Long term I think building true power means growing communities, joining unions and cooperatives. Most of us aren't rich or powerful enough to be heard, which is why organizing is so important. None of this is fair or easy to do.
