Louisiana lawmakers passed a new congressional map on Friday designed to strengthen Republican advantages in the state’s six U.S. House districts ahead of the 2026 midterm elections.

The map reduces the number of majority-Black districts represented by Democrats from two to one. It redraws Democrat Rep. Cleo Fields’ district to include more predominantly white communities in the Baton Rouge area and southern Louisiana, while adjusting boundaries around Democrat Rep. Troy Carter’s New Orleans-based district. Republican Gov. Jeff Landry is expected to sign the legislation into law.

The move comes one month after the U.S. Supreme Court struck down Louisiana’s previous court-ordered map as an illegal racial gerrymander, weakening key aspects of the 1965 Voting Rights Act. That ruling has triggered a wave of redistricting efforts in Republican-led Southern states as President Donald Trump pushes to protect and expand the GOP’s slim House majority.

Republicans currently hold four of Louisiana’s six seats. The new map aims to improve their position further, particularly protecting House Speaker Mike Johnson’s district. Similar efforts are underway in states like Florida, Tennessee, and Alabama, where Republicans see opportunities to gain as many as 14 seats nationally through redistricting. Democrats are expected to challenge the new Louisiana map in court.
