**Nine states—Alabama, California, Florida, Louisiana, North Carolina, Ohio, Tennessee, Texas, and Utah—will use newly drawn congressional maps for the November 2026 midterms.** This mid-decade redistricting wave, uncommon outside court orders, began after President Trump urged Texas Republicans to redraw lines in 2025 and accelerated following the U.S. Supreme Court’s April 2026 ruling in Louisiana v. Callais, which raised the bar for Voting Rights Act challenges and allowed maps previously struck down as racial gerrymanders to proceed if framed as partisan. Legislatures, commissions, and a California ballot measure enacted changes that shift seats toward one party or the other, with ongoing litigation in several states but current maps locked in for the election. Missouri’s proposed map was blocked by the Supreme Court, leaving the 2022 lines in place, while Virginia’s effort was invalidated. Primaries have adjusted in some states, and final outcomes hinge on any last-minute court actions before November 3.
