Congressional Maps Set for Midterms After Mid-Redistricting Push
One in ten US voters are in new districts for November, following a Supreme Court ruling in Missouri and map changes across nine states.

The congressional districts for the upcoming midterm elections are now finalized in every US state. This follows a mid-decade redrawing of maps that began after President Donald Trump urged a redraw in July 2025. The changes mean that one in ten potential voters will be in different districts than they were in 2024.
A US Supreme Court decision recently resolved a long legal battle in Missouri regarding which House map to use. The court ruled that Missouri must use the same map as the 2024 elections. Nine states have adopted new House maps during this period. Texas was the first to do so. Democratic-led California then responded by creating new districts intended to offset potential Republican gains in Texas.
Several Southern states joined the redistricting process after a Supreme Court ruling in April weakened federal Voting Rights Act protections for districts with large minority populations. According to an Associated Press estimate, the changes affect about one in ten potential voters nationwide. More than 6.9 million potential voters in Texas and over 6.3 million in California are in new districts. In Florida, more than 4.5 million voters face new boundaries. About 69% of Utah’s potential voters have new district numbers due to a state court decision.
The redistricting created ripple effects across multiple states. In Tennessee, Republicans targeted the Democratic-held 9th Congressional District in Memphis for major changes. This move resulted in even larger population shifts for the 5th Congressional District, which was previously based in central Tennessee. Seven of the state’s nine US House districts ended up with new boundaries.
