Rick Brattin

Missouri's 5th Congressional District, anchored in the Kansas City metro, will use the 2022 map rather than the 2025 redistricting plan for the November 2026 election, after the state Supreme Court ruled on the matter following legal challenges. The district, traditionally Democratic-leaning, pits longtime incumbent Rep. Emanuel Cleaver against Republican state Sen. Rick Brattin, who sued over primary disruptions caused by the map dispute, and Libertarian Randy Langkraehr. Cleaver, in office since 2005, has won previous races by wide margins, while Brattin is campaigning as a Trump ally focused on border security and spending cuts. The redistricting fight had aimed to dilute Kansas City's Democratic base across neighboring districts.

The U.S. Supreme Court blocked Missouri from using a Republican-drawn 2025 congressional map in November, requiring the state to instead use the map adopted in 2022. The ruling caps a monthslong dispute triggered by a national redistricting push, following mid-decade map changes in Texas and Ohio favoring Republicans and California's Democratic-leaning response. Missouri's 2025 map, passed in May, would have added a Republican-leaning seat by reshaping Kansas City's District 5, held by Democratic Rep. Emanuel Cleaver, and tightening District 2, held by Republican Ann Wagner.

Because primaries were held under the 2025 map while the general election reverts to 2022 lines, Republicans Bob Onder and Rick Brattin have sued, arguing voters' rights are harmed; the Eighth Circuit was set to hear arguments. Missouri's Supreme Court separately found Secretary of State Denny Hoskins in contempt for trying to use the blocked map, though he avoided sanction after complying. Voters will ultimately decide the matter through Proposition A, a ballot measure asking whether to adopt the 2025 map or keep the 2022 lines, with implications for other states' redistricting plans.

A dispute over which congressional map Missouri will use in November has moved into federal court as a ballot-change deadline looms. The Missouri Supreme Court ruled unanimously that a referendum petition from People Not Politicians was legally sufficient, meaning the 2025 GOP-favored map — drawn last September at President Trump's urging to create a 7-1 GOP advantage — cannot take effect until voters approve it, forcing a return to the old district lines under which much of Kansas City remains in Democratic Rep. Emanuel Cleaver's 5th District. The referendum will appear as Proposition A on the November 3 ballot.

Attorney General Catherine Hanaway has appealed to the U.S. Supreme Court, while Solicitor General Lou Capozzi asked a federal judge to block the state ruling on behalf of Secretary of State Denny Hoskins. Separately, U.S. Rep. Bob Onder, state Sen. Rick Brattin, and two voters sued to force use of the 2025 map, with Hoskins siding with them. People Not Politicians seeks dismissal, warning of chaos from last-minute changes. Decisions could come before Tuesday's deadline.

Cole County Circuit Judge Daniel Green ruled that Missouri's new, Trump-backed congressional map can be used in November's elections, rejecting a bid by the coalition People Not Politicians to force a statewide referendum on the redrawn districts. Green sided with Republican Secretary of State Denny Hoskins and GOP officials, finding the state constitution does not extend referendum rights to congressional redistricting and that swapping maps after the August primary would violate federal law. Opponents, including PNP director Richard von Glahn, immediately vowed to appeal to the Missouri Supreme Court, which upheld the map in May without ruling on referendum eligibility. Republicans, including Gov. Mike Kehoe and RNC Chairman Joe Gruters, celebrated the decision.

The map reshapes Democratic Rep. Emanuel Cleaver's Kansas City-based 5th District, pushing roughly 59% of its voters into new, rural Republican-leaning territory, and is expected to shrink Missouri's Democratic House delegation from two seats to one. The push, prompted by Trump's call for GOP-led states to redraw lines ahead of the midterms, has spurred litigation nationwide as Republicans and Democrats race to lock in favorable maps in states including Texas, North Carolina, California, and Utah, with control of the House at stake.
