Fact-Checking Ranked Choice Voting: Does It Actually Fix Polarization and Turnout?

As American political polarization reaches historic highs, a structural reform is sweeping across municipalities and states: Ranked Choice Voting (RCV). Currently used in nearly 50 cities, counties, and states—including statewide in Maine and Alaska—the system allows voters to rank candidates by preference rather than selecting just one.[3]

The core promise of the reform is transformative. Advocates argue that by eliminating the spoiler effect, the system encourages broadly popular candidates, reduces toxic negative campaigning, and boosts voter turnout. Yet, as the system scales, a counter-narrative has emerged from institutionalists and political scientists who warn that the reform may actually confuse voters, lead to ballot exhaustion, and fail to deliver on its utopian promises.[1][3][4][7]

To separate hope from empirical reality, the Factlen Editorial Team reviewed recent data from thousands of real-world elections, academic studies, and think-tank reports. The resulting evidence pack reveals a complex picture: while the system reliably alters how candidates campaign, its impact on voter turnout and deep-seated partisan polarization is far more nuanced than advocates often claim.[2][8][9]

Under a standard plurality system, the candidate with the most votes wins, even if they secure less than 50% of the total. In a ranked-choice system, if no candidate wins an outright majority of first-preference votes, an instant runoff is triggered. The candidate with the fewest first-preference votes is eliminated, and their voters' second choices are redistributed to the remaining candidates. This process repeats until one candidate crosses the 50% threshold, ensuring the victor has broad support.[1][5]

The strongest evidence in favor of the reform centers on campaign tone and the reduction of negative campaigning. Because candidates need to secure second- and third-choice votes from their opponents' supporters to survive the runoff rounds, they are structurally disincentivized from launching scorched-earth negative attacks.[1]

A comprehensive 2025 review by the American Bar Association found that voters in ranked-choice cities were twice as likely to report that local campaigns were a lot less negative compared to voters in plurality cities. Candidates in these races frequently refer to their opponents in more positive or neutral terms, actively courting cross-endorsements to build a broader coalition.[1][3]

However, the claim that this civility translates to a reduction in deep partisan polarization is heavily contested. A report published by the State of Maryland highlighted research suggesting that the system does not inherently decrease partisan animosity, and in some highly contested environments, it may even exacerbate it. While the reform can help moderate candidates survive primaries, researchers at the University of Chicago note that the theoretical benefits depend heavily on who decides to run and how voters strategically react.[2][7]

Advocates frequently cite the system as a tool to boost civic participation, arguing that giving voters more choices without the fear of wasting their vote brings more people to the polls. The empirical data provides conditional support for this claim, particularly in local and off-year elections where engagement traditionally lags.[3]

A 2026 analysis published by Illinois Wesleyan University found that in 2021 off-year elections, voter turnout was 17% higher in jurisdictions utilizing the reform compared to similar municipalities using traditional voting. This bump is largely attributed to increased direct campaign contact; because candidates must build broader coalitions, they engage in more grassroots mobilization and door-knocking.[1][6]

Yet, skeptics point out that these gains are not uniform. Some survey experiments indicate that a segment of the US electorate strongly prefers casting a single vote and finds ranking multiple candidates burdensome. Furthermore, critics argue that any turnout increases are often driven by the novelty of the system or concurrent competitive races, rather than the voting mechanism itself.[2][7]

The impact of the system on the election of women and candidates of color remains one of the most fiercely debated aspects of the reform. Proponents point to striking successes: a study of Bay Area elections found that 59% of offices filled via ranked-choice were held by women, and 60% by people of color, with female candidates showing a significantly higher likelihood of winning under these rules.[6]

Advocacy data also indicates that voters of color tend to utilize the ranking feature at high rates, often ranking more candidates on average than white voters. Because the system eliminates the fear of splitting the vote among similar candidates, multiple candidates from the same demographic or community can run simultaneously without cannibalizing each other's chances.[1][3]

Conversely, the Center for Election Confidence, citing research from Princeton political scientists, warns of a phenomenon known as ballot exhaustion. This occurs when a voter only ranks one or two candidates, and if those candidates are eliminated early, the voter's ballot does not factor into the final decisive rounds. The report argues that ballot exhaustion rates are disproportionately higher in minority voting precincts, potentially diluting their electoral influence.[4]

To understand the broader mechanical impact, the Institute for Mathematics and Democracy recently conducted what is believed to be the largest study of ranked elections, analyzing 4,000 real-world contests. Their findings confirm that the system effectively eliminates the spoiler effect and is highly resistant to strategic voting, consistently electing broadly acceptable candidates over fringe alternatives.[5]

Ultimately, the evidence suggests that the reform is a highly effective mechanical fix for specific electoral dysfunctions—namely, vote-splitting and plurality winners. It reliably forces candidates to campaign more constructively and ensures that the eventual winner has a mandate from a broader swath of the electorate.[1][8][9]

However, it is not a panacea for the deeper cultural and structural issues ailing American democracy. While it smooths the sharpest edges of campaign rhetoric, it cannot single-handedly dismantle entrenched partisan polarization or guarantee equitable representation without concurrent efforts to educate voters and simplify ballot design. As more jurisdictions adopt the reform, the focus will likely shift from whether it works in theory to how equitably it is implemented in practice.[2][7]
