BATON ROUGE, La. (AP) — Louisiana enacted a new map of congressional districts Friday that is designed to help Republicans pick up a seat while eliminating one of the state’s two majority-Black House districts, both of which are represented by Democrats.

Republican Gov. Jeff Landry signed the plan hours after it overwhelmingly passed the state’s Republican-controlled Legislature.

Approval of the new House map came a month after the U.S. Supreme Court struck down Louisiana’s current map — with its two majority-Black districts — as an illegal racial gerrymander, weakening the landmark 1965 federal Voting Rights Act. That decision intensified a national redistricting battle fueled by President Donald Trump’s efforts to protect Republicans’ slim U.S. House majority in the midterm elections. Louisiana is one of several Southern states now redrawing their maps to help Republicans.

Louisiana Republicans had considered drawing a map giving the party a shot at winning all six of the state’s U.S. House seats. But that would have required adding more registered Democrats to Republican-held districts, potentially backfiring with GOP losses.

The map approved Friday in a 28-10 state Senate vote along party lines reflected Republican arguments that a 5-1 map is safer for the GOP and better protects U.S. House Speaker Mike Johnson from facing a difficult reelection. Republicans currently hold four of Louisiana’s six congressional seats.
