In the 2022 election cycle, a group of Republicans and Democrats unsuccessfully sought to advance a ranked choice voting proposal in Missouri. That would have instituted nonpartisan primaries for statewide, congressional and state legislative elections. The top four candidates would advance to the general election, where voters could then rank candidates from favorite to least favorite.
If someone gets a majority of initial votes, they win. If no one gets a majority, the fourth place contender would be eliminated. And voters who ranked that candidate first would have their vote go to their second choice. This process would continue until a candidate gets a majority.
What a weak reason to amend the constitution.
