State legislature special sessions on congressional redistricting are becoming a major policy issue ahead of the 2026 midterm elections. In recent months, governors and lawmakers in several states have called or considered special sessions to redraw congressional maps outside the normal redistricting cycle. The activity reflects growing political and legal pressure surrounding control of U.S. House seats, voting rights litigation and changing interpretations of federal election law.
Mid-decade redistricting is relatively uncommon because congressional maps are traditionally redrawn after each decennial census. However, recent court rulings and shifting political dynamics have prompted renewed activity in states including Alabama, Florida, Georgia, Louisiana, Missouri, South Carolina, Tennessee, Texas and Virginia.
Why States Are Holding Special Sessions
Several states are using special sessions to revisit congressional maps after court decisions altered the legal framework surrounding redistricting and minority representation. Most recently the United States Supreme Court decided Louisiana’s 2024 congressional map was unconstitutional in Louisiana v. Callais.
Growing Activity:
-
- Florida’s special session produced a newly approved congressional map that quickly faced legal challenges under the state’s Fair Districts Amendment.
- In South Carolina, a push to convene a special redistricting session initially failed in the Senate before Republican Gov. Henry McMaster renewed efforts to bring lawmakers back to redraw congressional lines.
- Tennessee lawmakers moved rapidly through a special session early in May to approve a mid-decade congressional map overhaul targeting the state’s only Democratic-held congressional district in Memphis.
- Texas redistricting efforts have escalated into quorum battles and legislative walkouts after congressional map revisions were added to the governor’s special session agenda.
- The Virginia Supreme Court voted to invalidate a statewide redistricting referendum that voters had approved in April. The decision immediately halted implementation of the new congressional map and kept existing district lines in place for the 2026 elections.
State-Federal Implications
The recent increase in special sessions highlights how state legislative actions can shape national political outcomes. Because congressional district boundaries directly affect representation in the U.S. House, map changes in even a handful of states may influence the balance of power in U.S. Congress following the 2026 elections.
The issue has also intensified debate over the role of courts, legislatures and governors in the redistricting process. Ongoing litigation in multiple states is expected to continue shaping how and when congressional maps may be revised between census cycles.
In addition, policymakers and election officials are monitoring how compressed timelines could affect election administration, candidate filing periods and primary election schedules in states considering late-stage map changes.
FOCUS will continue to monitor developments on congressional redistricting special sessions across the country.
