Maine's election shows that ranked-choice voting is hot right now. But we have been here before

This week voters in the Pine Tree State chose to continue using ranked-choice voting in state-wide elections. Jack Santucci explains that ranked-choice voting is likely to be adopted in polarized political environments, creating majorities where there currently are none, and as a reaction to unpopular politicians who have won without majorities of votes. He reminds us that the current era of polarization is similar to that of one hundred years ago, the last time ranked-choice voting was in fashion.
