On August 24, a Maine state trial judge ruled that the Republican Party-backed referendum on ranked choice voting for president has enough valid signatures. Because it is now back on the ballot, ranked choice voting can’t be used in the upcoming election for president. In November, voters will vote again on whether to use ranked choice voting for president, but in the meantime it is not legally in force for that office. It is in force for Congress.
The basis for the ruling is that the Secretary of State had improperly invalidated signatures because the circulator in the town where they were gathered was not registered in that town. See this story.
The story does not mention that there is a separate state court lawsuit on whether the petitioning period for the referendum had already expired before the Republican Party circulated that petition.
