Black Democrats on Capitol Hill are raising alarms over Republican-led redistricting efforts, warning that the campaign will suppress Black voting power and undermine decades of civil rights advancements. The push, driven by President Trump and bolstered by a recent Supreme Court ruling curbing Voting Rights Act protections, has sparked protests from the Congressional Black Caucus (CBC), which is expected to lose several seats under new maps being drawn across Southern states.

The dispute centers on the Supreme Court's June decision in Louisiana v. Callais, where a 6-3 majority ruled that Louisiana violated the Constitution's equal protection clause by considering race when drawing a second Black-majority district following the 2020 Census. The ruling has triggered a wave of mid-decade redistricting in Republican-controlled states ahead of November's midterm elections.

What the Right Is Saying

Republicans have dismissed the accusations as political grandstanding and argue they are following constitutional principles by eliminating race as a factor in redistricting.

Speaker Mike Johnson (R-La.) pointed to Massachusetts — where 36 percent of voters supported Trump in 2024, but the entire House delegation is Democratic — as evidence that Democrats also engage in aggressive map-drawing. "We find it amusing that Democrats are suddenly concerned about 'fair congressional representation,'" Johnson told reporters last week. "And I challenge those Democrats to raise those concerns with the Republican congressmen from Massachusetts, Connecticut, or Rhode Island. They'll have a hard time doing that, of course, because Democrats have gerrymandered Republicans completely out of those states."

In the Louisiana v. Callais ruling, Justice Samuel Alito wrote for the majority that there was no evidence the old Louisiana map discriminated against Black voters and therefore race-based redistricting was not justified under the VRA. "Vast social change has occurred throughout the country and particularly in the South," Alito wrote.

What the Left Is Saying

Rep. Hank Johnson (D-Ga.) said the Supreme Court's decision has put Black communities back in a vulnerable position. "What they have done in eviscerating the Voting Rights Act is to put us back in a position where Jim Crow can be the rule of the day for Black people," Johnson said. "We are now, legally, in a posture where Black communities are not able to enforce a right to elect the representatives of their choice. And that is undemocratic, it's racist, it's wrong."

House Minority Leader Hakeem Jeffries (D-N.Y.), the first Black lawmaker to lead either party in either chamber, characterized the developments as an "unprecedented assault on Black political representation — the likes of which we have not seen since the Jim Crow era." "The ghost of the Confederacy has afflicted the United States Supreme Court majority and is invading and haunting the nation right now," Jeffries said.

Rep. Bennie Thompson (D-Miss.) rejected Republican claims that the dispute is purely partisan. "It has nothing to do with party, it's about race," Thompson charged. "Republicans are acting irrational by kicking Black folk out of Congress."

Rep. James Clyburn (D-S.C.), who faces a redrawn map designed to oust him after more than three decades in Congress, said the effort extends beyond voting rights. "This is not just about voting. I mean what does taking Jackie Robinson's contributions out of the Defense Department — what's that got to do with voting?" Clyburn asked. "There is a comprehensive approach on the part of this administration to turn the clock back to what I call Jim Crow 2.0."

Rep. Emanuel Cleaver (D-Mo.), 81, who is expected to lose his seat in Kansas City under new maps, said he hasn't seen such a coordinated effort since the 1960s. "We have not been this much of a target," Cleaver said. "I don't know if I would say that this is a complete turn to the Jim Crow era. But make no mistake, it's a return to some of the antics that we witnessed in the Jim Crow era."

What the Numbers Show

The Supreme Court's 6-3 decision in Louisiana v. Callais invalidated Louisiana's second Black-majority district, ruling it an "un unconstitutional gerrymander" that violated equal protection.

Tennessee became the first state to redraw its map following the ruling, carving up the Memphis-based district held by Rep. Steve Cohen (D-Tenn.) into three new districts, all favoring Republicans. Cohen announced his retirement at the end of this term, citing long odds of reelection under the new lines.

Louisiana's state Senate passed a new map Friday that eliminates one of the state's two current Black-majority districts. Alabama is moving on its own redistricting plan to remove one of two Black Democrats from Congress.

Rep. Steve Cohen noted that Republicans divided the Black vote roughly evenly between three new Tennessee districts — suggesting, he said, that GOP leaders had considered race even as they condemned Democrats for doing the same. "It's power, but it's definitely race, too," Cohen said.

The Congressional Black Caucus currently holds 58 seats in the House. The exact number of seats at risk under the new round of redistricting has not been independently calculated.

The Bottom Line

The Supreme Court's ruling and subsequent Republican map-drawing efforts represent a significant test for Black political representation in Congress, particularly in Southern states where Democrats have relied on majority-minority districts to elect Black representatives. Black lawmakers are framing the moment as existential, citing decades of progress that they say is now at risk.

Tennessee's actions — breaking up Memphis's Black voting bloc and prompting Cohen's retirement announcement — illustrate the immediate practical impact of the Supreme Court's decision. Similar efforts are underway in Louisiana, Alabama, and South Carolina, where Republican-controlled legislatures are moving quickly to redraw maps before November.

Republicans maintain they are following constitutional principles by removing race from map-drawing decisions, and have pointed to Democratic-controlled states as examples of their own gerrymandering. The dispute is likely to generate additional litigation as affected lawmakers and voting rights groups challenge new maps in court.
