Since the U.S. Supreme Court decided Louisiana v. Callais on April 29, two more states — Florida and Tennessee — have redrawn their congressional maps, Virginia’s map was blocked from certification by the Virginia Supreme Court, and the Alabama Legislature approved legislation that would set special primary elections in affected districts if courts roll back injunctions against previous Legislature-drawn maps. The Louisiana Legislature is still hearing proposals for a new congressional map after the Court struck down its current map in Callais.

On April 29, the Florida House and Senate both voted to approve a new map that would shift four U.S. House districts currently represented by Democrats to Republicans according to 2024 presidential election results. Governor Ron DeSantis (R) signed the map into law on May 4, 2026.

The Tennessee Legislature convened on May 5 for a special session on mid-decade redistricting. On May 7, the Legislature passed, and Gov. Bill Lee (R) signed into law, a new congressional map that aims to shift the state’s sole Democratic Memphis-area district to Republicans. 

Together, the Florida and Tennessee maps could bring the nationwide gains from redistricting to eight net districts for Republicans.

That figure does not include Virginia’s redrawn congressional map that would have shifted four additional districts toward Democrats. Mid-decade redistricting in Virginia required a constitutional amendment to allow the General Assembly to redraw the state’s congressional districts and return the responsibility of drawing congressional districts in 2031 to the Virginia Redistricting Commission. Voters approved the amendment on April 21, 2026, but the Virginia Supreme Court blocked its certification, ruling on May 8 that the state legislature violated procedural rules when it placed the measure on the ballot.

The table below shows the current status of mid-decade congressional redistricting nationwide:

More changes to congressional district boundaries could come.

On May 8, the Alabama Legislature approved legislation that would reschedule some 2026 primaries in the event that injunctions against the state’s 2023 congressional map are lifted in light of Callais. Alabama’s current congressional map was approved by a special master after the U.S. Supreme Court twice upheld lower court rulings blocking maps containing one majority-Black district. The bill would provide for special primary elections to be held in affected districts if “a federal court issues an order or vacates an injunction thereby allowing the Legislature to use a previously enacted legislative Congressional redistricting plan in the 2026 General Election.”

The South Carolina Legislature is considering a resolution to take up redistricting after the conclusion of its regular session on May 14. A bill to redraw the congressional map was introduced in the state House on May 7 and would aim to shift the 6th District, the state’s only Democratic district, to Republicans.
