The Florida Supreme Court has allowed new U.S. House districts drawn by Republicans to be used in the midterm elections, marking another victory for the GOP in a nationwide redistricting effort aimed at helping the party retain its slim House majority.

The court on Wednesday refused a request to issue a temporary injunction against the new districts.

Attorneys for voters who sued argued that the new House districts violate a state constitutional provision prohibiting partisan gerrymandering, and that the court should order the state to continue using the same districts as in the previous election.
