Republicans are rapidly pursuing redistricting efforts across the South following a U.S. Supreme Court ruling that affects majority-Black congressional districts. Alabama, Tennessee, Louisiana and South Carolina are all considering changes. Tennessee lawmakers have proposed a new House map that would divide Memphis, a majority-Black city. They pressed ahead with it on Wednesday, despite protests. In South Carolina, Republican leaders are targeting a district held by a longtime Black Democratic lawmaker. Alabama lawmakers are proposing a new congressional primary if courts allow the state to redistrict. Louisiana already has postponed its congressional primary to allow time for a new redistricting plan.

Republicans have won a partisan redistricting battle for Congress. The GOP could gain about 10 U.S. House seats in the upcoming November elections if the new voting districts perform as intended. The question is whether that will be enough for the GOP to maintain a majority in Congress. Democrats need only a few seats to take control. Political trends and historical patterns favor Democrats. President Trump's approval ratings are negative, and the incumbent's party has lost House seats in every midterm election over the past two decades.
