A wave of mid-decade congressional redistricting, launched by Texas Republicans in a 2025 special session following presidential urging, has produced new maps in nine states for the 2026 midterms after the U.S. Supreme Court’s April 2026 Louisiana v. Callais ruling narrowed Voting Rights Act constraints on district lines. Legislatures in Florida, North Carolina, and Tennessee enacted voluntary changes, while Ohio’s commission approved updated boundaries and courts or ballot measures finalized lines in Alabama, California, Louisiana, and Utah. Missouri’s revised map was blocked for November use, and Virginia’s effort was invalidated. Litigation remains active in multiple states, though most boundaries are now fixed ahead of primaries and the general election, shifting the composition of roughly a dozen competitive districts relative to 2024 maps.
