Ranked-choice voting asks voters to rank candidates by preference. Election officials then count up all of the first choices, and if one candidate earns more than 50% of the vote, they win. If no candidate gains a majority of votes, the candidate with the lowest support is eliminated. If your first choice is eliminated, your second choice is counted. This process is repeated until one candidate receives more than 50% of the vote. RCV ignores all your preferences besides your first choice unless your first choice is eliminated. This means that good consensus candidates can be eliminated in the first round. Approval voting simply allows voters to vote for as many candidates as they wish, and the candidate with the most votes wins. Approval voting is simpler and cheaper than RCV and counts all of your preferences when votes are totaled.
