Ranked-Choice Voting

How Ranked-Choice Voting Works in Practice

Ranked-Choice Voting (RCV), also known as instant-runoff voting, allows voters to rank candidates in order of preference instead of selecting just one. In an RCV election, if no candidate wins a majority of first-choice votes, the candidate with the fewest votes is eliminated. Voters who selected the eliminated candidate as their first choice then have their votes reallocated to their second-choice candidate. This process continues in rounds until a candidate achieves a majority, ensuring the winner has broad support.

Why Ranked-Choice Voting Matters

RCV addresses some common problems in plurality or "first-past-the-post" systems, such as the spoiler effect where similar candidates split the vote, allowing a less popular candidate to win. By enabling voters to express preferences without fear of wasting votes, RCV encourages more honest voting and can lead to more representative outcomes. It also promotes positive campaigning because candidates aim to be the second or third choice of their opponents' supporters.

Ranked-Choice Voting vs. Approval Voting

While both RCV and approval voting aim to improve electoral fairness, they differ significantly. Approval voting lets voters select all candidates they approve of without ranking them; the candidate with the most approvals wins. In contrast, RCV requires ranking candidates and uses an elimination and redistribution process to find a majority winner. Approval voting is simpler but may not always yield a majority-supported winner; RCV guarantees a majority winner but involves more complex counting.

Real-World Examples of Ranked-Choice Voting

Several U.S. cities such as San Francisco, Minneapolis, and Portland use RCV for local elections. Maine was the first state to adopt RCV for statewide federal elections, including congressional and gubernatorial races. Internationally, Australia uses a form of RCV, called preferential voting, for its House of Representatives, demonstrating RCV's viability in diverse political contexts.

Common Misconceptions About Ranked-Choice Voting

One misconception is that RCV is too complicated for voters to understand. Studies have shown that with proper voter education, most voters find RCV intuitive and easy to use. Another myth is that RCV always benefits certain political parties; in reality, its impact varies depending on local political dynamics and voter preferences. Lastly, some worry RCV is more expensive to administer, but costs are often comparable to traditional systems once initial setup and education are complete.
