turning off voters is the biggest reason why we don't vote imo in this environment and there's nothing you can do about shitty choices that the democrats will give us; but there's things you can do to overcome the other institutional part of it; aka gerrymandering:

setup free voting ride shares with free filling snacks in gerrymandered states that will pick each person up from home; drop them off at their polling station; pick them up from there; and then drop them off at home w/o having to wait for everyone to finish voting. the lines are VERY long and take hours in heavily gerrymandered places like houston texas and people hate voting already; so making them wait or skip dinner to vote is a non-starter.

setup free voting phone number and/or website that will help register you to vote (not just tell you what you need to do) on your behalf and include the option to mail you a pre-filled envelope and stamp if paper registration is required. advertise it HEAVILY on all forms of media everywhere and make it clear it's not from the government.

then, assign a case worker to every client to ensure that the registration was completed and followup on the problems that gerrymandered places usually create to suppress votes. also get lawyers or people familiar with election laws to file inquiries on each voter's behalf each time a gerrymandered place manages to find a reason to disqualify a voter or an employer refuses to let them off to vote and use that case worker to manage it.

expect it to fail the first few times because people hate talking about politics so they won't listen for the first few cycles.
