US Redistricting 2026 After Supreme Court Ruling Explained
Alabama and Tennessee lead major map changes as US redistricting 2026 accelerates after a key Supreme Court ruling.
Alabama and Tennessee have become the latest southern states to move toward redrawing their congressional districts, following a recent Supreme Court decision that further weakened the Voting Rights Act.
Both states’ Republican governors announced plans to convene special legislative sessions next week. Tennessee Governor Bill Lee said the goal is to ensure that congressional districts reflect the preferences of voters across the state. His announcement came shortly after Alabama Governor Kay Ivey called lawmakers back to Montgomery to address potential changes to district boundaries and to consider holding special primary elections for affected races.
These rapid developments highlight how quickly some Republican-led states are responding to the court’s ruling. The decision has opened the door for revisiting maps that had previously been drawn to ensure minority voters could elect candidates of their choice.
With Republicans holding only a narrow majority in the US House, redistricting has become a high-stakes political battle nationwide. Both major parties have been attempting to gain an edge through map changes, but the latest ruling has intensified efforts—especially in the South, where the Voting Rights Act has historically played a major role in shaping electoral districts.
The Supreme Court’s decision on Wednesday eliminated a majority-Black district in Louisiana, making it more difficult to challenge redistricting plans on the grounds of racial discrimination. It is the latest in a series of rulings by the court’s conservative majority that have reduced the scope of the landmark 1965 law.
Supporters of scaling back the law argue that conditions in the country have changed significantly since the civil rights era. Alabama Attorney General Steve Marshall, speaking to CNN, said the state today is very different from what it was in the early 1960s.
At the same time, the announcements from Alabama and Tennessee reflect growing pressure from national Republican leaders and activists. Initially, Governor Ivey had suggested Alabama would not pursue redistricting, as the state is currently under a court order preventing such changes until after the 2030 census. However, state officials have since taken steps to challenge that restriction in court.
Ivey said the special session, scheduled to begin Monday, is being called in anticipation of a favorable legal outcome. Alabama’s current congressional delegation includes five Republicans and two Democrats, following a court-mandated addition of a second district with a substantial Black population.
In Tennessee, any redistricting effort is expected to focus on the Memphis-based district represented by Democrat Steve Cohen, the only Democratic member of the state’s congressional delegation. The state legislature is set to reconvene on Tuesday.
Election timelines could also be affected. Alabama’s primary is currently set for May 19, while Tennessee’s is scheduled for August.
Meanwhile, Louisiana officials recently announced a delay in the state’s US House primaries as lawmakers work on a new map. Although ballots have already been sent to overseas voters, officials say votes cast in the May election for House races will not be counted. The move has already prompted legal challenges from voters and civil rights groups.
Other southern states controlled by Republicans are also facing calls to revisit their district maps. In South Carolina, several gubernatorial candidates have urged lawmakers to consider changes that could weaken longtime Democratic Representative Jim Clyburn’s position. Although the Supreme Court previously upheld the state’s existing map, Governor Henry McMaster said it would be reasonable to review it to ensure compliance with federal law and the Constitution.
South Carolina’s legislature remains in session, with primary elections scheduled for June 9.
