Supreme Court narrows voting law, lifting GOP odds of keeping House
· Axios

The Supreme Court limited a key provision of the Voting Rights Act Wednesday, handing a loss to civil rights groups.

Why it matters: The ruling could reshape voting all across the South and could boost the Republican majority in the House by an additional 19 seats when compared to 2024 maps.
- The Louisiana v. Callais ruling does not erase Section 2 of the Voting Rights Act, but it effectively neuters it. The court rewrote the test used to apply Section 2 in such a way that it can only take effect as long as protected seats don't infringe on the right of state lawmakers to draw partisan gerrymanders.
Driving the news: 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."
The big picture: The court effectively narrowed Section 2 of the civil rights law, which prohibited racially-discriminatory gerrymandering.
- Section 2 helped end Jim Crow laws and expanded voting protections for people of color across the South, particularly for Black Americans.
Yes, but: Some opponents of the law have said that because the 14th Amendment limits the use of race in redistricting, using Section 2 to remedy racially discriminatory maps is, in fact, racial gerrymandering.
- Partisan gerrymandering was already a shield in racial-gerrymandering cases: Lawmakers could argue they drew GOP maps, not anti-Black ones.
- The Callais decision goes further. It says partisan goals can also help protect maps against Voting Rights Act lawsuits.
Catch up quick: Louisiana has been locked in a bitter court feud over its congressional maps since 2020, with civil rights groups, lawmakers and other interested parties jockeying to implement new districts.
- Black voters, which make up roughly 30% of the state's population, successfully sued to add a second majority-Black district in Louisiana in 2022, arguing that they were underrepresented.
- Lawmakers updated their maps in response, but a group of non-Black voters sued the state after, accusing lawmakers of relying too heavily on race to create the new maps.
- A three-judge panel agreed in 2024, setting the stage for the High Court's ruling.
Zoom in: "Section 2 of the Voting Rights Act of 1965 was designed to enforce the Constitution — not collide with it," Alito wrote.
- "Unfortunately, lower courts have sometimes applied this Court's §2 precedents in a way that forces States to engage in the very race-based discrimination that the Constitution forbids."
The other side: In a dissent, Justice Elena Kagan argued that the majority opinion "threatens a half-century's worth of gains in voting equality."
- "Under the Court's new view of Section 2, a State can, without legal consequence, systematically dilute minority citizens' voting power," she wrote.
- "The Callais requirements have thus laid the groundwork for the largest reduction in minority representation since the era following Reconstruction."
Worth noting: Florida Gov. Ron DeSantis was betting on the Supreme Court's decision to aid his own mid-decade redistricting push, assuming the high court would strike down the civil rights law before it even issued its ruling.
- The ruling doesn't erase Florida's separate ban on partisan gerrymandering.
- Unlike in other states, Florida lawmakers can't simply defend a map by saying they drew it for partisan gain — unless state courts also accept DeSantis' broader argument that the entire Fair Districts Amendment no longer applies.
What they are saying: The Voting Rights Act "was the guardrail," April Albright, of advocacy group Black Voters Matter told Axios' Chelsea Brasted in December.
- Its demise means that "there's nothing left, because most of these red states also don't have robust protections for voting rights in their own state constitutions." Go deeper: How a Supreme Court case could reshape the South's congressional representation
