Political subdivisions establishment or enforcement of ranked-choice voting prohibition

Minnesota Senate File 639 prohibits cities, counties, townships, and school districts from adopting or enforcing ranked-choice voting (RCV) for local elections. The bill bans any local rule, ordinance, or charter provision that establishes RCV - a system where voters rank candidates by preference - or similar voting methods. It specifically states that such local efforts would be void, applying to all local offices within these political subdivisions. The law takes effect the day after final enactment for elections held on or after that date.
