What Is Missouri Amendment 4?
Protect Majority Rule Missouri is a campaign committee that opposes Amendment 4, a measure that would alter the rules for citizen-led initiative petitions in Missouri.
What Amendment 4 Would Change
Currently, citizen-led ballot initiatives pass with a simple statewide majority. Amendment 4 would require these measures to win a majority in every one of Missouri's eight congressional districts. Legislative referrals to the ballot would remain subject to the simpler standard, applying the stricter rule only to citizen initiatives.
Potential Impact
Under Amendment 4, a ballot initiative could fail even if it wins the overall statewide vote, if it falls short in any one of the eight districts. Opponents argue this could allow a small fraction of the electorate to block measures supported by the majority of Missouri voters, undermining the citizen initiative process that has existed since 1908.
