Ballots not counted in the final round of Maine's primary earlier this month because they did not rank the candidates who ended up being the final two. It was the first time ranked-choice voting was used for a statewide election in the U.S.
*CORRECTION: A previous version of this indicated that 8,889 ballots were filled out incorrectly because they did not rank all of the candidates. That is inaccurate. Voters are not required to rank all of the candidates.
