Volunteers, groups that already expend effort to educate populations on voting, fucking pamphlets. There are plenty of ways to spread information somewhat reliably. I’m not even saying to avoid implementing rank-choice. I think it would be a net benefit, but I also think concerns over education on the new system are valid. Implementing something like this improperly opens the door to the entire concept being poisoned for the rest of the public, and we should be talking about how a lack of knowledge regarding the new system can inadvertently suppress voters.
