One in 10 voters face new congressional districts in November
Supreme Court ruling locks in Missouri's 2024 map, while nine states adopt new boundaries ahead of midterms.

Voters in nine states will cast ballots in redrawn congressional districts for the November midterm elections. This change follows a mid-decade redrawing of maps spurred by President Donald Trump in July 2025.
The U.S. Supreme Court recently resolved a legal dispute in Missouri. The court ordered the state to use the same House map as in the 2024 elections. This decision ended a long-running battle over which district lines to apply.
Texas was the first state to adopt new House districts after the presidential push. Democratic-led California followed by drawing new lines to counter potential Republican gains in Texas. Several Southern states later redrew maps after an April Supreme Court ruling weakened federal Voting Rights Act protections for districts with large minority populations.
An Associated Press estimate indicates that one in ten potential voters nationwide are in different districts than in 2024. Texas has more than 6.9 million potential voters in new districts. California has over 6.3 million, and Florida has more than 4.5 million. In Utah, a state court decision resulted in new district numbers for about 69% of potential voters.
Redistricting created ripple effects across multiple states. In Tennessee, Republicans targeted the Democratic-held 9th Congressional District in Memphis for major changes. This move caused larger population shifts in the 5th Congressional District, which was previously based in central Tennessee. Seven of the state's nine U.S. House districts ended up with new boundaries.
