Louisiana lawmakers have approved a congressional map that would give Republicans another pickup opportunity, sending it to Gov. Jeff Landry for final approval.

The Louisiana state Senate approved the new lines on Friday, a day after the state House did so. The newly drawn map would favor Republicans in five out of six House districts, eliminating one of two majority-Black districts that elected Democrats in 2024.

It comes a month after the Supreme Court invalidated Louisiana’s existing map and weakened the Voting Rights Act, setting off a renewed wave of redistricting efforts across the South.

Once Landry signs the bill as expected, Louisiana would become the second state to adopt new district lines since the Supreme Court ruling. Tennessee adopted a map this month that eliminates the one district currently held by a Democrat, prompting Rep. Steve Cohen to announce his retirement. 

But other states have faced challenges in revisiting their maps ahead of the November elections. Efforts to do so by Republicans in South Carolina stalled this week after some Republicans sided with Democrats to halt the process as early voting kicked off ahead of next month’s primary elections.

Separately, a federal court blocked Alabama from using a new congressional map that would eliminate a second Black opportunity district in the state, although state officials have asked the Supreme Court to halt that ruling.

After those setbacks this week, the action in Louisiana on Friday was a win for Republicans and for President Donald Trump, at whose urging the redistricting fight kicked off last summer. Still, the map could face additional legal challenges, and more uncertainty is expected in both red and blue states ahead of the 2028 elections. 

Democratic Rep. Cleo Fields, whose district was essentially eliminated under the new Louisiana map, has not said whether he would seek reelection in the revised 6th District, which would favor Republicans. Fields returned to Congress last year after the current map created a second majority-Black district, similar to one he previously represented in the mid-1990s.

The new map also has its detractors among Republicans. Rep. Clay Higgins said on social media Thursday that he was “100% opposed to this latest and worst iteration of proposed Louisiana Congressional districts.”

“This map is the worst I’ve seen yet, and I’ve seen many,” he said on X. “This Frankenstein looking thing was NO DOUBT drawn up by a very small handful of guys in a secret room. NOBODY should support this insanely bad map.”

After the Supreme Court ruling, Landry delayed the state’s House primaries until November to allow for more time to reconsider the district lines. Under the new plan, all-party primaries would be held on Nov. 3 — Election Day — with any necessary runoffs delayed until December.
