The Supreme Court ruled 6-3 on Wednesday that Louisiana's congressional map creating a second majority-Black district amounted to an unconstitutional racial gerrymander, a decision that sent California's top Democrats scrambling to warn of dire consequences while Republicans celebrated a landmark shift in redistricting law.
The ruling, in Louisiana v. Callais, found that the state unconstitutionally added a second majority-Black House district and that Section 2 of the Voting Rights Act did not justify the race-based mapmaking. The decision narrows how the Voting Rights Act can be used in future redistricting disputes and could open the door to map redraws across the country, particularly in states where Democrats relied on racial considerations to draw favorable lines.
Justice Samuel Alito, writing for the six-justice conservative majority, left no room for ambiguity about the constitutional stakes.
"That map is an unconstitutional gerrymander," Justice Alito wrote. "Correctly understood, Section 2 does not impose liability at odds with the Constitution, and it should not have imposed liability on Louisiana for its 2022 map."
Alito went further, as the Washington Examiner reported, writing that "allowing race to play any part in government decisionmaking represents a departure from the constitutional rule that applies in almost every other context." The majority opinion did not fully overturn the longstanding Gingles framework for evaluating Voting Rights Act claims, but it narrowed the test significantly, requiring stronger proof that race, rather than politics, drove the drawing of district lines.
Justice Elena Kagan dissented sharply. She wrote that the court's "gutting of Section 2 puts that achievement in peril," AP News reported.
The loudest reactions came not from Louisiana but from California, where Democratic officials treated the ruling as an existential threat to their political project.
Gov. Gavin Newsom took to X to frame the decision as part of a long pattern of erosion. "The Supreme Court majority continues to gut the Voting Rights Act and vital protections for our democracy and fair representation," Newsom wrote. He called for "nationwide reforms" to "ensure our founding ideals and the greatest experiment in democracy on earth makes it another 250 years."
Newsom also vowed action from Sacramento:
"California will not sit back, we will continue to uphold what makes us American, and take action, over and over again, to safeguard our democracy for the generations to come."
What Newsom did not address is the obvious question: if drawing districts primarily around race is unconstitutional, what does that mean for California's own maps? The state has used racial and ethnic "communities of interest" as a major factor in shaping its congressional and legislative districts, a practice that now faces a much higher legal bar.
The Supreme Court's recent willingness to let GOP-friendly maps stand in Texas already signaled which direction the justices were heading on redistricting disputes. Wednesday's ruling confirmed it.
State Attorney General Rob Bonta, who has been defending California's redistricting approach in court, called the decision "deeply disappointing." He invoked the Voting Rights Act's history.
"Since 1965, Section 2 of the Voting Rights Act has helped ensure that all Americans, regardless of their race, have an equal opportunity to exercise their constitutional right to vote."
Bonta then acknowledged uncertainty about the ruling's reach while previewing a familiar Democratic argument, that any pullback on race-conscious mapmaking will inevitably lead to voter suppression.
"While the full impact of this ruling is still uncertain, we know from past experience that decisions striking down, or effectively gutting, provisions of the Voting Rights Act are often followed by new state laws that restrict access to the ballot for voters of color."
That framing skips a step. The court did not strike down Section 2 of the Voting Rights Act. It ruled that Section 2 cannot be used to justify maps that the Constitution forbids. There is a meaningful difference between restricting ballot access and telling a state it cannot sort voters by race when drawing congressional lines.
Redistricting fights have consumed courts and legislatures across the country in recent years. A Virginia judge recently blocked redistricting vote certification in a separate dispute that underscored just how politically charged the mapmaking process has become.
Former House Speaker Nancy Pelosi called the ruling a "devastating blow" and warned of broad consequences.
"The consequences will be felt across the country: fewer voices heard, fewer communities represented and a democracy diminished."
Pelosi urged Congress to pass the John R. Lewis Voting Rights Advancement Act, which would require states with recent histories of voter discrimination to obtain federal approval before changing voting laws. "Congress must urgently pass the John R. Lewis Voting Rights Advancement Act to restore the full strength of the Voting Rights Act before this latest blow becomes fatal," she said.
That legislation has no realistic path through a Republican-controlled House. Pelosi knows this. The call reads less like a governing proposal and more like a fundraising prompt.
On the other side, California Assemblymember David Tangipa, who sued Gov. Newsom over the state's redistricting push, welcomed the ruling and told California to "get ready to redistrict."
"No more prophylactic racial gerrymanders. From the Prop 50 congressional maps to state legislative seats, where race heavily shaped districts (esp. for Latino 'communities of interest' without proven dilution), it's time for just, race-neutral maps that represent all Californians, not racial balancing."
Tangipa's argument goes to the heart of what the court decided. For years, Democratic mapmakers in California and elsewhere used racial demographics as a primary tool for shaping districts, often under the banner of the Voting Rights Act. The Supreme Court has now raised the bar for that practice, requiring proof that racial discrimination actually occurred before race can dominate the line-drawing process.
The growing number of redistricting controversies reaching state courts suggests that the legal ground is shifting fast beneath the feet of officials who relied on race-first mapmaking.
The ruling's consequences extend well beyond Louisiana. Legal observers say the decision could weaken Section 2 challenges to redistricting maps in multiple states, particularly across the South. Newsmax reported that the National Republican Congressional Committee hailed the decision as a constitutional and political victory.
NRCC Chairman Richard Hudson framed the ruling in terms of equal treatment under the law:
"Today's decision is a victory for the Constitution and the principle that every American citizen is equal under the law. The Supreme Court made clear that our elections should be decided by voters, not engineered through unconstitutional mandates."
AP News reported that the ruling could encourage additional redistricting across the country and may help Republican efforts to maintain or expand control of the House in future election cycles. That tracks with the broader political math: if race-based districts that packed minority voters into safe Democratic seats are redrawn on race-neutral grounds, some of those seats become competitive.
Democrats have long used the Voting Rights Act as both a legal tool and a moral shield for drawing maps that favored their candidates. The court's majority has now said, plainly, that the Constitution does not permit racial sorting of voters even when it is done in the name of representation.
The political dynamics of state-level court battles over partisan control will only intensify as the implications of this decision ripple outward.
The open questions are significant. How far will the ruling's logic reach into existing maps? Which states will face new legal challenges? Will California's own districts survive scrutiny under the tighter standard? Bonta himself admitted the "full impact of this ruling is still uncertain."
What is certain is that the era of drawing congressional maps with race as the dominant factor, and then invoking the Voting Rights Act as an unassailable defense, is over. The court did not abolish Section 2. It did not say race can never be considered. But it did say that the Constitution comes first, and that mapmakers cannot gerrymander by race and then claim they were required to do so.
California Democrats are treating this as a crisis. California Republicans are treating it as an opportunity. Assemblymember Tangipa's lawsuit against Newsom over the state's maps now carries considerably more weight. The court's conservative majority has shown it is willing to enforce constitutional limits on racial preferences in mapmaking, even when doing so upends political arrangements that Democrats spent years building.
For decades, the left treated race-conscious redistricting as settled law and moral high ground. The Supreme Court just reminded them it was neither.
