**Nine states—Alabama, California, Florida, Louisiana, North Carolina, Ohio, Tennessee, Texas, and Utah—are using newly drawn congressional maps for the November 2026 midterms.** This marks an unusual mid-decade redistricting cycle outside the standard post-census process. The shift began in summer 2025 when Republican-led legislatures responded to presidential calls for map revisions favoring their party, starting with Texas. A subsequent U.S. Supreme Court ruling in *Louisiana v. Callais* narrowed Voting Rights Act constraints on majority-minority districts, prompting additional changes in several Southern states. Democratic-led California countered with its own voter-approved revisions. Most new maps face ongoing legal challenges, though recent court decisions have largely locked in the boundaries for this election cycle. Missouri’s revised map was blocked, leaving its prior lines in place. These alterations affect roughly one in ten potential voters nationwide and could shift the partisan balance of several House seats.
