By 60-Point Margin, Missouri Voters Reject GOP Push to Make Ballot Measures Harder to Pass

By 60-Point Margin, Missouri Voters Reject GOP Push to Make Ballot Measures Harder to Pass Voters also rejected an amendment that would have gradually eliminated the state’s income tax in what one Democratic mayor said would benefit the wealthy “while raising costs on hardworking families.” Julia Conley Common Dreams The Democratic mayor of Kansas City, Missouri was among those celebrating what he called the “TOTAL repudiation by Missouri voter of a core agenda of state GOP leadership” on Tuesday night after the state voted by a 60-point margin against Amendment 4, a measure backed by the Republican governor which would have weakened voters’ ability to pass citizen-sponsored ballot initiatives. “We took over control of the state of Missouri tonight, repudiating absolutely atrocious ideas,” Mayor Quinton Lucas said in a video message addressing voters as election results came in. “Against millions of dollars, lots of special interests, Missouri voters are trouncing Amendment 4, which was going to take away our initiative petition rights, eliminate our ability to make sure we can get things done.” The Republican supermajority in the state Legislature and Gov. Mike Kehoe supported Amendment 4, which was spurred by the passage of a ballot initiative in 2024 that had added the right to abortion care to the Missouri Constitution. The addition of the amendment to the constitution would have required a majority vote in each of the state’s eight congressional districts in order to pass any future citizen-sponsored amendments, instead of a simply majority of voters across the state. With more than 95% of votes counted on Wednesday morning, 80.3% of voters had rejected Amendment 4, while 19.7% had supported it. The amendment would have created the highest threshold in the country for passing ballot initiatives like others that Missourians have passed in recent years, including ones that have legalized marijuana, raised the minimum wage, and expanding Medicaid coverage. Opponents warned that under Amendment 4, an initiative could fail to pass even with as many as 95% of voters across the state supporting it. The St. Louis American reported that the election result could signal voters’ coming rejection of Amendment 3 in November, which would ban abortion in Missouri in most cases.
