Creates provisions for ranked-choice voting

This bill mandates the use of ranked-choice voting and instant runoff voting for all primary and general elections in Missouri, requiring candidates to secure a majority of votes rather than just a plurality to win. Under this system, voters rank candidates in order of preference, and if no candidate achieves a majority in the first count, votes for eliminated candidates are redistributed to the voter's next preferred choice until a winner emerges. The legislation also requires the state secretary of state to run a voter education campaign and prohibits the purchase of new voting machines that cannot support ranked-choice voting starting in 2025. Additionally, it provides specific rules for handling ties, managing ballots where voters rank multiple candidates equally, and filling multiple seats in a district.
