For all the criticism surrounding U.S. electoral systems–whether it be gerrymandering, campaign spending, or election integrity–there is little discussion of a particular system which offers several potential improvements to the current election process: ranked-choice voting.
Many of us have heard the term, but what actually is ranked-choice voting? Ranked-choice voting, or RCV, is a system in which voters rank their preferred candidates on the ballot by first choice, second choice, third choice, and so on. If a candidate has the majority of first-choice votes, they win the election. If no candidate receives a majority, the candidate with the fewest first-choice votes is dropped from the race, and the ballots which listed the dropped candidate as their first choice now contribute their second choices, and so on. This process of removing the least-voted-for candidate continues until there is a candidate with a majority. RCV is sometimes called “instant runoff” because there is no need for subsequent elections; voters have indicated their preferences in the event that their first choice or even their second or third choice does not get elected. RCV is already used in municipal elections in some major US cities, including San Francisco and New York City.1
Advocates for RCV list several benefits. For one, RCV seems to improve voter experience. Based on a Y2 Analytics poll of Utah voters in the 2021 municipal elections, 86% were satisfied with the voting experience, reporting it was “easy to use” with clear instructions.”2 In addition, since a ranked-choice system levels the playing field for candidates, voters feel freer to choose candidates with whom they feel aligned on values rather than simply picking the person they think is most likely to win. According to a 2022 survey conducted by Alan James Simmons et al., “Researchers asked survey respondents to vote in a hypothetical version of the 2020 US presidential election between Joe Biden (Democrat), Donald Trump (Republican), Howie Hawkins (Green), and Jo Jorgensen (Libertarian). Among respondents randomly assigned to vote under plurality rules, 3.75% voted for Hawkins or Jorgensen; among respondents randomly assigned to vote under RCV, 7% ranked Hawkins or Jorgensen first.”3 This indicates that voters are more likely to vote for third-party candidates in an RCV system.
Another benefit of RCV is that policy is more likely to reflect voter preferences. In a “first-past-the-post” voting system like we use in the U.S., most candidates seek the support of interest groups and major political parties to propel them towards election. As a result, such groups can motivate public elected officials to make policy decisions based on seeking party support instead of passing laws that voters want.4 RCV, on the other hand, creates incentives for candidates, once elected, to adopt moderate policy positions “with the knowledge that the extremists will be eliminated in the first round of the runoff.”5
Lastly, RCV systems seem to increase voter turnout. According to a 2024 study of voter data conducted by Eveline Dowling and other researchers, “results show that people in RCV jurisdictions are significantly more likely to vote in off-year elections than individuals living in non-RCV places.”6 This may be because voters tend to interact more with candidates and campaigns in RCV elections.7
Not only does RCV improve the voting process, but it also seems to contribute towards a better overall experience for candidates. In a RCV system, candidates must appeal to all groups of voters in order to win, not just their own base. As Dowling and Tolbert explain, “this need for broader appeal can lead to more civil and cooperative campaigning.”8 Campaigns also become less negative, since candidates don’t want to “engage in negative campaigning” or malign the images of their opponents, as these actions “could alienate potential supporters.”9
RCV also encourages more candidates to run for office, as voters are free to cast their vote more sincerely.10 Unlike in a plurality or majority electoral system, candidates have a chance of winning even without the support of a major political party due to the ranking system.
Despite its benefits, RCV certainly comes with some drawbacks. In a climate where Americans already distrust elections, decreased voter trust in the electoral system is a legitimate concern. Derek Monson et al. found that “39% of Americans do not trust the fairness of elections in the U.S.,” which does not bode well for changing the voting system.”11 Additionally, there is evidence of voter mistrust in RCV specifically. In a recent study, participants were given a scenario in which RCV and first-past-the-post systems yielded different election outcomes. The study found that US survey respondents were generally more accepting of the first-past-the-post outcome.12 Implementing RCV could exacerbate voter skepticism surrounding elections, which could be seriously damaging to democracy in the U.S.
Another frequently cited concern is a phenomenon known as ballot exhaustion. Ballot exhaustion occurs when all of a voter’s chosen candidates on a ballot have been eliminated due to runoff and there are more than two candidates left in the race. Then, the ballot would be considered exhausted13 because it no longer contributes a tally for the final winner.
Ballot exhaustion has raised questions about whether or not RCV is constitutional. In 2011, Dudum v. Arntz challenged San Francisco’s ranked-choice voting system (known as Instant-Runoff Voting, or IRV) for city officials.14 San Francisco law limited the number of rankings on each individual ballot to three, so plaintiffs argued that “when more than four candidates run for a particular office, the IRV excludes exhausted voters from full participation.”15 Although the Ninth Circuit Court ultimately upheld IRV as constitutional, questions certainly remain regarding whether or not RCV conforms to the Constitution in all its various forms.
Overall, RCV provides key improvements to the current U.S. voting system; however, it still has several drawbacks that cannot be ignored. Before considering implementing RCV in major elections, more data is needed to help predict the effects such a system would have in the U.S. Other countries such as Italy and Brazil have implemented RCV more broadly, but their government systems are much different than that of the U.S., which makes it difficult to directly compare and predict the potential consequences of widespread institutionalization of RCV in the U.S. The public must also be educated about RCV so that they can develop well-formed opinions on the system and perhaps build more trust in its legitimacy. Still, even if the data advocates for the U.S. to implement RCV, it is ultimately the voters’ decision whether or not to do so. True to RCV’s principles of representation, moderation, and amplifying voters’ unique preferences, the American public will have to decide whether there is more merit or fault in RCV.
