New congressional maps are still possible in Alabama and Louisiana, while South Carolina will use its existing congressional map again this year. 

After new congressional maps took effect in Florida and Tennessee earlier this month, 2026 redistricting pursuits are a wrap in all but a few states. A panel of federal judges blocked Alabama's 2023 Legislature-drawn congressional map after the Supreme Court vacated previous injunctions against it, and Alabama made an emergency appeal back to the Court. Louisiana's Legislature is still working toward a new map ahead of a June 1 deadline. South Carolina's Senate adjourned a special redistricting session without passing a new map. 

On May 11, the Supreme Court vacated lower court injunctions that had blocked Alabama from using a congressional map the Legislature drew in 2023 and remanded the case for reconsideration in light of the Court's decision in Louisiana v. Callais. On remand, the three-judge federal district court enjoined Alabama from using its 2023 map, writing that it was “tainted by intentional race-based discrimination.” The state appealed the following day, and Justice Clarence Thomas ordered plaintiffs to respond by June 1 at 4 p.m.

The South Carolina Senate voted 24-20 on May 26 against ending debate on the redistricting bill. The Senate then adjourned the special session, which Gov. Henry McMaster (R) had called after the regular session ended May 14. The bill, which had already passed the House, would have redrawn the state's congressional map to shift Democrat James Clyburn’s district toward Republicans ahead of this year’s midterms.

In Louisiana, the Senate passed a new congressional map on May 14 on a 27-10 party-line vote. The map would redraw one of the state's two majority-Black districts, potentially shifting the state's delegation from a 4-2 Republican-to-Democrat to a 5-1 split. The House and Governmental Affairs Committee approved an amended version on May 21. The two chambers are working on a compromise version ahead of the special session’s June 1 end date.

Together, if Alabama's 2023 map is allowed to take effect for the November general election and Louisiana enacts its new map, mid-decade redistricting efforts would sum to 10 net congressional districts for Republicans.
