Supreme Court Blocks GOP Effort to Redraw Missouri Congressional Map

The U.S. Supreme Court has blocked a Republican-backed congressional map in Missouri, impacting the GOP’s chances to gain an extra House seat. The decision disrupts Republican efforts to control Congress. Missouri’s use of the 2022 map, mandated by the state’s Supreme Court, becomes more likely.

With the rejection of the new map, Republicans face a major setback in their strategy to secure additional seats. The GOP holds a narrow majority in the House, intensifying their need for new maps. President Donald Trump has strongly supported such redistricting efforts in Republican states.

Newsweek asked the White House for comments, but has not yet received a response.

Republican Redistricting Efforts in Missouri

Missouri Republicans aimed to make the Kansas City-area district, held by Democrat Emanuel Cleaver, more competitive for GOP candidates. This change would create an additional Republican-leaning district, shifting their advantage to seven seats from six.

The proposed map would modify the 5th Congressional District, extending it into rural Republican areas. The Associated Press estimated up to 59% of voters in the district would be new under the proposal. Though used in the August primary, the map’s use in November was blocked by Missouri’s Supreme Court pending a referendum.

The issue reached the U.S. Supreme Court, which upheld the lower court’s decision. This creates a scenario where Missouri could have different districts in the general election than in the primary.

Implications for National Redistricting Efforts

The Missouri case is part of a larger national redistricting conflict ahead of the 2026 midterm elections. Despite the setback in Missouri, Republicans have succeeded in other states. They have effectively redrawn maps in nine states, aiming to secure 15 additional seats. Democrats have only one new map, crafted in California, hoping to gain five seats there.

Republican-led states like Texas and Florida have pursued advantageous redistricting. Meanwhile, courts have intervened in states like North Carolina, reshaping political landscapes before elections. Overall, the GOP remains ahead in the national redistricting battle.
