Missouri Judge Upholds Trump‑Backed Mid‑Decade U.S. House Map
Jackson County Circuit Judge Adam Caine on Thursday rejected a lawsuit challenging Missouri’s new U.S. House districts, a map backed by President Donald Trump and drawn in a 2025 special session to give Republicans a stronger chance to unseat Democratic Rep. Emanuel Cleaver in the Kansas City–area 5th District. Voters who sued argued the plan violated the state constitution’s requirement that districts be compact, saying the 5th District was "radically" stretched east into rural, Republican‑leaning counties and split Kansas City in unprecedented ways. The state, represented by Republican Attorney General Catherine Hanaway’s office, countered that while the 5th may be less compact, the map overall is more compact and splits fewer local governments, an argument Caine accepted while stressing that which municipalities to divide is a political judgment for the legislature. The ruling is a clear win for Missouri Republicans and the Trump White House, which pressured state lawmakers to revisit the 2022 map and has pushed similar partisan redistricting fights in other states, but the lines still face a separate challenge at the Missouri Supreme Court over whether mid‑decade redistricting is constitutional. Opponents have also submitted more than 300,000 signatures seeking a statewide referendum on the map, setting up parallel legal and political battles over who controls Missouri’s role in determining the next House majority.
