The U.S. Supreme Court struck down Louisiana’s congressional map and sharply limited the use of race in drawing district boundaries in a major ruling that could carry significant consequences for future House elections.
In comparison to 2024 maps, the decision could increase the Republican dominance in the House by an extra 19 seats and alter voting throughout the South.
Louisiana had been ordered by lower courts to create a second majority-Black congressional district in 2024 to comply with Section 2 of the 1965 Voting Rights Act, which bars states from diluting minority voting strength.
The Trump administration and state officials challenged the revised map, arguing it amounted to an unconstitutional racial gerrymander in violation of the 14th Amendment, which guarantees equal protection under the law, reports said on Wednesday.
In a majority opinion, Justice Samuel Alito said that “because the Voting Rights Act did not require Louisiana to create an additional majority-minority district, no compelling interest justified the State’s use of race in creating SB8, and that map is an unconstitutional racial gerrymander.”
About one-third of Louisiana’s residents are African-American, and the state’s only two Democratic lawmakers in Congress (compared to four House Republicans) were elected from majority-black districts.
The ruling carries immense weight, with two prominent voting rights organizations noting earlier that the removal or restriction of Section 2 will likely empower Republican-led legislatures to change the boundaries of as many as 19 congressional districts to their advantage, in order to comply with the court.
“However, it’s not clear if red states will be able to seize on the Supreme Court’s decision in time to significantly impact the 2026 midterms, in which Democrats are favored to retake the House of Representatives,” the New York Post reported.
This would enable mapmakers to emphasize Republican strengths.
Voting rights organizations aligned with the Democratic Party already warned that the removal or restriction of Section 2 could empower Republican-led legislatures to change the boundaries of as many as 19 congressional districts to their advantage.
Fair Fight Action and the Black Voters Matter Fund argue that if Section 2 of the Voting Rights Act is invalidated, it could significantly increase the likelihood that Republicans will maintain control of the House of Representatives for years.
Research has identified 27 congressional seats nationwide that Republicans could benefit from if the current legal and political landscape remains unchanged.
Nineteen of these changes are directly tied to the potential loss of Section 2 protections.
The SCOTUS ruling will prompt many states to redraw maps ahead of November’s elections.
On Friday, the Virginia Supreme Court struck down a Democrat-inspired gerrymandered congressional map that would have given the party four of the five seats currently held by Republicans in a state that is about as evenly divided as any in the country.
“On March 6, 2026, the General Assembly of Virginia submitted to Virginia voters a proposed constitutional amendment that authorizes partisan gerrymandering of congressional districts in the Commonwealth. We hold that the legislative process employed to advance this proposal violated Article XII, Section 1 of the Constitution of Virginia. This constitutional violation incurably taints the resulting referendum vote and nullifies its legal efficacy,” said the 4-3 ruling.
“Virginians voted by a wide margin” in 2020 “to reform the redistricting process in the Commonwealth in an effort to end partisan gerrymandering,” the ruling continued. “They adopted Article II, Section 6-A of the Constitution of Virginia to create the Virginia Redistricting Commission. Under the 2020 amendment, if this bipartisan commission could not reach a consensus, the responsibility to achieve the amendment’s ultimate goal — ridding political partisanship as much as possible from the redistricting task — would become the constitutional responsibility of the Supreme Court of Virginia.”
“In 2021, partisan disputes in the Virginia Redistricting Commission deadlocked the 16-member commission. When the task fell to us pursuant to Article II, Section 6-A, we unanimously ordered that the prior district maps be replaced with wholly new maps that commentators across a wide spectrum of political views later deemed to be free of partisan bias,” the ruling noted further.
The court said that the Democrat majority in the state legislature earlier this year then decided to put a new politically gerrymandered map to a vote of the people.
The amendment narrowly passed with barely 50 percent of the vote for and about 47.8 percent against.
