Which states could get new congressional maps in 2024?

An updating tracker of developments in midcycle redistricting.

After the 2020 census, each state redrew its congressional district lines (if it had more than one seat) and its state legislative districts. 538 closely tracked how redistricting played out across the country ahead of the 2022 midterm elections. So everything is done and dusted, right?

Not so fast, my friend. More than a half-dozen states face the prospect of having to go through the redistricting process again, mostly due to federal and/or state litigation over racial or partisan gerrymandering concerns. Both Democrats and Republicans have the opportunity to flip seats in districts drawn more favorably than they were last cycle. For example, Democrats appear poised to pick up at least one seat in Alabama and could theoretically get more favorable maps in Louisiana and Georgia. Republicans, meanwhile, could benefit from more favorable 2024 maps in North Carolina and New Mexico.

We’ll be using this page to relay major developments in midcycle redistricting, such as new court rulings and district maps, and examine how they could affect the political landscape as we move deeper into the 2024 election cycle. We’ll predominantly focus on congressional maps, but will share the occasional key update on conflicts over state legislative districts.

Louisiana’s congressional map is so back

On Wednesday, the Supreme Court reinstated a version of Louisiana’s congressional map that contains two Black-majority, Democratic-leaning districts — at least for the 2024 election.

Last month, a lower court had struck down that map for relying too much on race. But the Supreme Court temporarily put that ruling on hold, saying it was too close to the election to change the map. Interestingly, the court’s six conservatives voted to reinstate the map, while the three liberals dissented, even though the map will almost certainly cause Republicans to lose a House seat. In a solo dissent, Justice Ketanji Brown Jackson didn't argue against the outcome itself but wrote that she believed the court intervened too early.

Louisiana’s new congressional map struck down

A panel of three federal judges struck down Louisiana's new congressional lines on Tuesday, surprisingly throwing a last-minute twist into the 2024 congressional map.

Earlier this year, the Louisiana legislature redrew the state's congressional map to add a second Black-majority district after a court ruled that the old map violated the Voting Rights Act by not giving Black voters enough representation. This turned a solid-red seat, the 6th District, into a solid-blue seat, giving Democrats a near-guaranteed pickup this fall.

But the new 6th District was awkwardly shaped, stretching diagonally across the state from Shreveport to Baton Rouge, giving rise to complaints it was a racial gerrymander — essentially, that it was drawn based on race above all else. These three judges agreed, saying the district violated the 14th Amendment's equal protection clause.

That doesn't necessarily mean Louisiana won't get a second Black-majority, safely Democratic district, though. It's easy to draw such a district that's more compact, going from Baton Rouge up the Mississippi River. It remains to be seen what the state will do next; the judicial panel will meet again on May 6 to discuss next steps.

South Carolina will use its old congressional map in 2024

Time's up, Supreme Court! That's what a panel of three federal judges declared on Thursday, as they decided that South Carolina must use the congressional map it used in 2022 in the 2024 election as well.

The panel had previously struck down South Carolina's 1st District as a racial gerrymander because it did not have enough Black voters, which had turned the one-time swing district into a more safely Republican seat. However, Republicans appealed that ruling to the Supreme Court, which has been sitting on the case for months. The three-judge panel finally decided that it was too late to make any changes for 2024, given that Monday is the deadline for congressional candidates to file to run. As a result, Democrats will miss out on a chance to flip another district in their favor this year.

Wisconsin won’t get a new congressional map

On Friday, the Wisconsin Supreme Court declined to hear a challenge to the state's congressional map. The order was a blow to Democrats, who had argued that the map unfairly advantaged Republicans. It was also unexpected after liberals took control of the court with the election of Janet Protasiewicz in April 2023; Protasiewicz did not participate in the order.

As a result, Wisconsin will use its current congressional map, which has six Republican-leaning seats and two Democratic-leaning seats, in the 2024 election.
