The U.S. Supreme Court handed another win to Republicans on Tuesday night, allowing Alabama to use a GOP-friendly congressional map in this fall’s election that will decide control of the Congress.

The justices overturned a lower court ruling that the redistricting plan approved by the Legislature intentionally discriminates against black voters. In so doing, it cleared the way for a map first approved in 2023 that is likely to give Republicans a 6-1 advantage in its congressional delegation.

“At this preliminary stage, the State has shown that it is entitled to interim relief from the District Court’s injunction,” the justices in the majority opinion wrote.

“The State has also made a strong showing of irreparable harm and that the equities and public interest favor it,” they added.” We have repeatedly cautioned that lower federal courts should not ‘alter the election rules on the eve of an election.’”

The court’s three liberal justices all dissented.

The ruling is the latest win for President Trump and Republicans in a redistricting battle both parties have pursued in hopes of gaining an advantage in the November elections.
