The 2020 presidential election took days to be decided, but it’s possible that 2024 could take even longer, thanks to a specific voting process used in two states that aren’t typically the focus of national political campaigns.
Maine and Alaska each use ranked choice voting to determine the winners of their electoral votes for president, and with independent Robert F. Kennedy Jr. on the ballot in Maine and aiming to qualify for access in Alaska, it’s more likely that this process will come into play.
Under the system, voters rank the candidates in order of preference. If someone wins a majority of first-choice votes, that candidate is elected. But if not, voters’ other choices are used to determine a winner.
