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.

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.

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.

This week, New York's Democratic-controlled legislature took up the congressional map proposed by the state's bipartisan redistricting commission … and largely left it unchanged.

On Monday, after the legislature voted down the commission's proposal, many people assumed they would replace it with an aggressive Democratic gerrymander that would help the party in its quest to flip the U.S. House. But that's not what happened. Instead, the legislature passed a map with only minor tweaks from the commission's, which in turn was pretty close to the old congressional map drawn by a court-appointed special master in 2022.

Based on the results of the 2020 presidential election, no district will shift by more than 4 percentage points of margin. The biggest change is in the 22nd District, which now would have voted for Biden by 11 points, making it harder for Republican Rep. Brandon Williams to win reelection. Democratic Reps. Tom Suozzi and Pat Ryan also got a little safer in their districts, while the legislature also did a favor for Republican Rep. Nick LaLota, turning his 1st District from a narrow Biden district to a narrow Trump district.

Gov. Kathy Hochul signed the new map into law on Wednesday night.

On Wednesday, North Carolina Republicans released two proposed congressional maps for the 2024 cycle, both of which strongly favor the GOP and would allow the party to flip three or four House seats from Democrats.

North Carolina’s congressional delegation currently consists of seven Republicans and seven Democrats, but the first proposed map creates 10 reliably Republican seats, three reliably Democratic seats and one competitive seat. The second proposal is even more aggressive, creating 11 Republican-leaning districts and three Democratic-leaning ones.

Both maps would likely doom the reelection chances of Democratic Reps. Kathy Manning, Wiley Nickel and Jeff Jackson. The first proposal would also make it harder, though not impossible, for Democratic Rep. Don Davis to win reelection, moving his district from one that voted for President Biden by 7 percentage points to one that voted for Biden by just 2. The second proposal would merge Davis and Democratic Rep. Valerie Foushee into the same safely Democratic seat (the 1st District), so one of them would have to retire or lose in a primary.

The North Carolina legislature will discuss these proposals in committee on Thursday, but it’s unclear when they will be voted upon or which plan (if either) will eventually be enacted. In North Carolina, the governor does not have veto power over redistricting maps, so the Republican-controlled Senate and House will have free rein to pass whichever map they can agree on. Democrats may sue over the eventual map, however, especially if the legislature picks the more aggressive proposal. That map dilutes the share of the Black voting age population in the 1st District from 41 percent to 39 percent and could be vulnerable to a legal challenge under the Voting Rights Act.
