Fact-Checking Ranked-Choice Voting: Does the Evidence Match the Promises?

The American electoral system is undergoing its most significant structural shift in a century. Across the country, the traditional "choose one" plurality voting method is increasingly being replaced by Ranked-Choice Voting (RCV). As of 2026, more than 50 municipalities and several states have adopted the system for public elections, fundamentally altering how campaigns are run and won.[4]

The premise of RCV is straightforward: rather than selecting a single candidate, voters rank candidates in order of preference. If no candidate secures an outright majority of first-choice votes, the lowest-polling candidate is eliminated, and their voters' second choices are distributed to the remaining field. This instant-runoff process repeats until one candidate crosses the 50 percent threshold.[7]

Advocates promise that this simple mechanical change can cure many of modern democracy's ailments—reducing toxic polarization, eliminating the "spoiler effect" for third-party candidates, and forcing politicians to campaign more civilly. Skeptics counter that the system is overly complex, depresses turnout among marginalized groups, and leads to discarded ballots. To separate political rhetoric from empirical reality, we examined the peer-reviewed data and municipal outcomes from the past decade.[7]

The first major claim is that RCV improves campaign civility. The theoretical mechanism here is compelling. In a plurality system, candidates are incentivized to attack their opponents to suppress their turnout. Under RCV, candidates must court their opponents' supporters to secure crucial second- or third-choice votes, making scorched-earth tactics mathematically risky.[3]

The evidence largely supports this claim, particularly in local elections. A comprehensive study published in Politics & Governance analyzed mayoral races in cities with and without RCV. Researchers found that candidates in RCV cities were significantly less likely to use negative attack ads, and voters in those cities perceived campaigns as noticeably more positive and issue-focused.[3]

However, the data on national or highly partisan races is less definitive. While candidates may refrain from attacking ideologically adjacent rivals—knowing they need those second-choice votes—they still frequently attack candidates on the opposite end of the political spectrum. The civility effect appears strongest within primary elections or nonpartisan municipal races where ideological overlap is higher.[6]

The second major claim centers on voter confusion. Opponents frequently argue that the complexity of ranking multiple candidates will frustrate voters, leading to lower participation, particularly among older voters or those with lower educational attainment. They warn that a confusing ballot is inherently disenfranchising.[2]

The empirical data presents a nuanced but generally positive picture. According to the MIT Election Data and Science Lab, voter turnout does not significantly decrease when a jurisdiction transitions to RCV. In fact, because RCV often replaces low-turnout off-cycle runoff elections with a single, higher-turnout general election, overall participation in deciding the final winner frequently increases.[1]

Furthermore, voter comprehension appears remarkably high. Exit polling and ballot analysis from the Bipartisan Policy Center indicate that across multiple state and municipal rollouts, over 85 percent of voters report finding the ranked ballot "easy" or "very easy" to understand. The learning curve is real, but it is steep and brief, typically resolving entirely after a single election cycle.[2]

Despite high comprehension, a phenomenon known as "ballot exhaustion" remains a genuine vulnerability of the system. This occurs when a voter ranks only one or two candidates, and those candidates are eliminated in early rounds. If the voter has not ranked any of the finalists, their ballot becomes "exhausted" and does not factor into the final round.[1]

Data from the National Conference of State Legislatures shows that in multi-round RCV elections, the ballot exhaustion rate averages between 9 and 11 percent. This means the ultimate winner may secure a majority of the remaining ballots, but not necessarily a majority of the total ballots cast in the election.[4]

Election administrators note that ballot exhaustion is largely a function of voter choice rather than systemic failure. Voters are not required to rank every candidate. If a voter genuinely has no preference among the remaining field, an exhausted ballot accurately reflects their political will. Nonetheless, it complicates the claim that RCV always guarantees a true mathematical majority winner.[4]

The third major claim is that RCV eliminates the "spoiler effect" and aids third parties. In traditional plurality voting, a third-party candidate often siphons votes from the major-party candidate they most closely align with, inadvertently helping their ideological opposite win. This dynamic forces voters to choose between their true preference and the "lesser of two evils."[5]

The evidence here is robust and unambiguous: RCV effectively neutralizes the spoiler effect. Research demonstrates that voters can safely rank their true favorite first—even if that candidate is a longshot—knowing that if their candidate is eliminated, their vote will seamlessly transfer to a more viable backup option without penalizing their broader political coalition.[5]

This dynamic has demonstrably diversified candidate pools. Knowing they will not be accused of "spoiling" a race, more women, minorities, and non-traditional candidates have entered RCV contests. Stanford University researchers found that RCV municipalities consistently see a higher percentage of minority candidates running for and winning local office compared to similar plurality cities.[6]

The final and most ambitious claim is that RCV reduces political extremism. Because winning requires broad acceptability across the electorate to secure second and third choices, the system theoretically favors consensus builders and penalizes polarizing figures who command a loyal base but alienate the broader public.[2]

The data provides moderate support for this, though the sample size of highly polarized RCV races remains limited. In state-level implementations, candidates who relied entirely on a narrow, highly partisan base have struggled to cross the 50 percent threshold in later rounds, often losing to candidates who built broader, more moderate coalitions.[2]

Ultimately, the evidence suggests that Ranked-Choice Voting is not a magical panacea for all democratic dysfunction, nor is it the confusing disaster its harshest critics claim. It is a mechanical tool that reliably eliminates the spoiler effect, modestly improves campaign civility, and empowers voters to express their true preferences without fear of wasting their vote.[7]
