Ranked-Choice Voting
Ranked-choice voting lets you rank candidates in order. If no one wins more than half, the last-place candidate is dropped. Their votes move to each voter's next choice. This repeats round by round, until someone passes half.
What it is
Ranked-choice voting (RCV) lets you rank candidates in order of preference -- a first choice, then a second choice, and so on. It is also called "instant runoff voting." Here is how the count works. First, officials count all the first-choice votes; if one candidate has more than half, that person wins right away. If no one does, the last-place candidate is dropped, and each of their ballots moves to its next choice. The count repeats, round by round, until someone reaches a majority -- more than half. San Francisco is one California city that uses RCV. What does the research show? One large study looked at 182 U.S. ranked-choice elections from 2004 to 2022 and found that RCV's feared math problems "are rarely observed in real-world elections." But it did find one real weakness: sometimes a ballot runs out of ranked choices before the final round, something experts call "ballot exhaustion." When it happens often, the winner may not hold a majority of all votes cast. Other research finds RCV "was not associated with a statistically significant change in voter turnout in general elections." Experts largely agree on how RCV works; they disagree about whether its trade-offs are worthwhile.
How it works
Most U.S. elections use "plurality" voting, meaning whoever gets the most votes wins, even if it is under half. With three or more candidates, the vote can split, and a less-popular candidate may win with only about 35%. People also worry about "spoilers" -- minor candidates who pull just enough votes to flip the result. RCV was designed to ease these problems by letting you mark backup choices. So why do people debate it? It really comes down to trade-offs. Supporters say RCV lets you vote for who you truly like without "wasting" your vote, and that winners end up with broader support. Critics say it is more complicated, and that the winner may not hold a real majority, because some ballots run out of choices before the end. RCV does not split neatly by party: in California, Democratic Governor Jerry Brown vetoed a 2016 bill to expand it, while many reform groups strongly support RCV. Each party has both supporters and opponents.
The debate — equal weight, both sides
Your vote should never work against you. In plurality voting, backing your favorite can help elect the person you like least, so people vote for "the lesser of two evils." RCV removes that fear. As the reform group FairVote puts it, with RCV "voters don't need to worry about 'spoilers,' or feel forced to vote for the lesser of two evils." You rank your true favorite first and add a safe backup second -- if your favorite cannot win, your ballot still counts for your next choice. RCV also aims to give winners real majority support: FairVote argues that RCV winners hold majority support and better represent the people they serve, and that RCV lets more candidates run without splitting the vote among allies. RCV may even calm nasty campaigns: candidates also want to be your second choice, so they have less reason to attack rivals. FairVote argues this pushes them to campaign in a more positive way, and neutral research backs this up -- one review found voters in RCV cities were "nearly twice as likely to say local campaigns were 'a lot less negative.'" Turnout can rise too: FairVote Minnesota reports that "RCV contributed to a 10% increase in turnout in the Minneapolis-St. Paul area." Rank your heart, and keep your voice.
A vote should be simple and clear: you study the candidates, you pick the one you want, and the top vote-getter wins. Critics say RCV trades that clarity for confusion. Even some Democrats agree -- California's Democratic Governor Jerry Brown vetoed an RCV expansion in 2016, writing: "Ranked choice voting is overly complicated and confusing. I believe it deprives voters of genuinely informed choice." Their biggest worry is ballot exhaustion: when it happens, critics say, it builds a fake majority. The Heritage Foundation, a conservative think tank, says RCV "disenfranchises voters" to "manufacture a faux majority for the winner." The numbers can be striking -- a peer-reviewed study of four California and Washington elections found "the winner in all four of our cases receives less than a majority of the total votes cast," and the Alaska Policy Forum, studying RCV races nationwide, found "the eventual winner failed to receive a true majority 61 percent of the time." A regular runoff, critics argue, is cleaner: the top two candidates face off, voters choose again, and the winner has a true majority and a clear final choice.
