The topics of single-winner and multiwinner elections merit separate discussions.
For legislatures, multiwinner elections with Proportional Representation (PR) would make a very democratic representation. And some systems for achieving PR use ranking ballots. So, there are some uses and contexts for which I do not necessarily condemn ranked-choice voting (RCV). I judge it pretty OK for the multiwinner case.
To make single-winner elections anywhere near democratic, to honor the spirit of “one person, one vote”, or to give any chance to candidates not having big-money support or fame, or to resist the spoiler effect and vote splitting strongly enough, it is necessary to enact evaluative voting. Three evaluative systems are Approval Voting, Score Voting, and STAR Voting. None of these uses ranking ballots. The single-winner case of RCV is called IRV, instant runoff voting. IRV, even under its new marketing name RCV, is a dangerous siren song that holds up a false solution and distracts activists from real solutions for the single-winner arena. Whether they know it or not, IRV advocates are working very effectively in support of continued oligarchy, the predictable consequence of which is omnicide.
Fargo and St. Louis enacted Approval Voting by referendum.
