Missouri voters rejected Amendment 4, a Republican-led effort to increase the passage threshold for citizen-led constitutional amendments.
Missouri voters defeated Amendment 4, a proposal that would have required citizen-led constitutional amendments to win a majority in each of the state's congressional districts rather than a simple statewide majority. The measure was first proposed by Republican state Rep. Ed Lewis to protect the state's Constitution from being overly influenced by special interests. While supporters argued the current process allowed for too many progressive priorities to pass, opponents heavily outspent the backers, pouring millions into broadcast ads to secure the victory. Missouri Gov. Mike Kehoe expressed disappointment with the defeat, noting that the administration announced the measure was a common-sense solution for transparency and integrity. Kehoe stated that while Amendment 5, which sought to eliminate the state income tax, also failed, he remains committed to pursuing conservative policies that help families keep more of their earnings. The victory for Amendment 4's opponents ensures that the state's direct democracy process remains accessible for voters to legislate directly by petitioning to place amendments on the ballot.
