Missouri Voters Reject Republican Income Tax and Ballot Measures

Missouri voters rejected two Republican-backed constitutional amendments in a landslide election, with both measures failing in every county across the state. Amendment 5, which proposed replacing the state income tax with broader sales taxes, received only 16.6% support. Amendment 4, which would have required citizen-led amendments to win both statewide and in all eight congressional districts, received 19.7% support.

Alex Riley, the Missouri House Majority Leader, attributed the defeats to flawed versions of the proposals rather than a rejection of the underlying concepts. He noted that while no-income-tax states are performing well, any future attempts to modify the income tax space would look different.

Democratic leaders characterized the results as a sign of voter frustration with one-party rule. Missouri Democratic Party Chairman Russ Carnahan described the outcome as a seismic shift, arguing that the Republican-controlled legislature has drifted from its constituents. State Senator Stephen Webber and State Representative Betsy Fogle added that the amendments reflected the priorities of major donors over the needs of the electorate.
