In a surprise move, Maine lawmakers passed a bill Monday extending ranked-choice voting to presidential primary and general elections, though it’s unclear if Gov. Janet Mills backs it. She could stop it from taking effect before the 2020 election.
The proposal from Senate President Troy Jackson, D-Allagash, would put Maine further in uncharted territory on ranked-choice voting. A 2016 referendum made it the first state to adopt ranked-choice voting statewide, but legislative tweaks motivated by conflicts with the state Constitution have limited its use to congressional elections and state primaries.
