Several states have enacted new congressional district maps since the 2024 elections through legislative action or court orders, altering boundaries for the 2026 midterms in places including California, Florida, Missouri, North Carolina, Ohio, Tennessee, Texas, and Utah. Republican-led legislatures initiated most of these mid-decade redraws, often seeking to consolidate or dilute Democratic-leaning areas, while California voters approved a Democratic counter-map via ballot measure in November 2025. Ongoing litigation in Alabama, Georgia, and Louisiana could produce further changes before candidate filing deadlines or primaries, with a recent Supreme Court ruling on race-based districting accelerating efforts in some Southern states. These shifts reflect standard redistricting procedures where state legislatures and governors control map approval, subject to legal challenges that may delay final maps until closer to election day.
