On June 11, the Maine legislature passed LD 1666. The Senate vote was 20-14; the House vote was 72-70. It changes the definition of “ranked choice voting” to say that the system is a system which elects candidates who won a plurality. The bill doesn’t actually change how RCV works; it is a vocabulary tweak.
The reason this matters is that the State Supreme Court years ago interpreted the State Constitution to ban RCV in general elections for state office. That is why Maine uses RCV for federal primaries and federal general elections, and also uses it for state office primaries, but does not use it for state general elections. The backers of the bill hope that this vocabulary change will lead the State Supreme Court to approve RCV for state office general elections.
