Mid-decade congressional redistricting has produced new House maps for the 2026 midterms in Alabama, California, Florida, Louisiana, North Carolina, Ohio, Tennessee, Texas, and Utah. Republican-led legislatures in Texas, Florida, North Carolina, and several Southern states enacted changes after a Supreme Court ruling weakened Voting Rights Act constraints on majority-minority districts, while Ohio’s bipartisan commission acted under state rules. Democrats countered with a voter-approved legislative map in California. Missouri will use its 2022 lines after courts blocked the 2025 version pending a November referendum, and Virginia retained prior boundaries. Ongoing litigation in multiple states and late primary adjustments under new lines continue to shape which maps reach Election Day.
