**Mid-decade congressional redistricting has produced new maps in multiple states ahead of the 2026 House elections, driven primarily by Texas’s voluntary redraw in August 2025 at the urging of President Trump, followed by Democratic countermeasures and a wave of additional changes after the Supreme Court’s April 2026 Louisiana v. Callais decision limited Voting Rights Act challenges to majority-minority districts.** States that have implemented new maps include Alabama (SCOTUS-cleared 2023 lines), California (voter-approved Proposition 50), Florida, Louisiana, North Carolina, Ohio (bipartisan commission), Tennessee, Texas (SCOTUS-upheld), and Utah (court-ordered). Missouri’s enacted map was blocked for the general election, with the 2022 lines in use and a November 2026 referendum pending; Virginia’s attempt was struck down. Ongoing litigation in several states, candidate filing deadlines, and primary postponements in places like Louisiana continue to shape which boundaries reach voters, with trader focus on final legal resolutions and any last-minute court or legislative shifts before Election Day.
