A key part of the New York City mayoral races was Ranked Choice Voting.
I'm not seeing many news articles mention this yet (correct me if I'm wrong though!).
Ranked choice let's us vote first for who we actually want.... and then put in backup votes for "good enough" candidates and allows us to compromise and find common ground.
It destroys the concepts of "lesser of two evils" and "throwing away your vote".
I hope we see Ranked Choice voting everywhere.
