Ranked choice voting (RCV) will again be employed in congressional and state races in Maine and Alaska, allowing voters to rank candidates in order of preference. This method aims to ensure that the eventual winner achieves a majority of votes, even if voters' initial top choices are third-party candidates.

Under RCV, voters list candidates from first to last choice. If no candidate secures over 50% of the initial first-place votes, the candidate with the fewest votes is eliminated. Their votes are then redistributed to the next highest-ranked choice on those ballots until a candidate reaches a majority.

This system has been in place in Maine since 2018 and in Alaska for the past four years. However, it has also sparked considerable debate regarding its effectiveness and the learning curve for voters. Opposition to RCV has grown, with 19 states having banned the practice.

On November 3, Alaskans will vote on a ballot measure that could repeal the state's adoption of RCV, potentially joining the list of states that prohibit its use. Researchers emphasize the importance of examining both the advantages and disadvantages of RCV as the discussion continues among voters.

Ismar Volić, director for the Institute for Mathematics and Democracy at Wellesley College, explained that RCV allows voters to support a candidate they favor, even if that candidate has a low chance of winning, by ranking another preferred candidate second. This can mitigate the "spoiler effect," where a third-party candidate draws votes away from a major candidate, potentially altering the election outcome.

David McCune, a mathematics professor at William Jewell College who studies RCV, noted that a significant impact of this voting method is the reduced influence of spoiler candidates. The system is designed to ensure that the winning candidate has broader support, as reflected by the transfer of votes through multiple rankings.

While RCV systems typically use computer programs for vote tallying, which often leads to quick results, the learning curve and the perceived complexity have been points of contention for some voters and officials. The ongoing debates highlight the differing perspectives on how RCV impacts electoral fairness and voter engagement.

As Alaska prepares to vote on its RCV measure, the outcomes in both states will be closely watched, potentially influencing the future adoption or rejection of ranked choice voting in other jurisdictions across the country.
