Matt Gromlich is in the news because Louisiana’s congressional map has been redrawn, with lawmakers approving a new plan that is expected to favor Republicans and could still face legal challenges. The changes come after the Supreme Court struck down the previous map and forced delays in the state’s House elections. The new map would eliminate one majority-Black district and leave the state with a 5-1 Republican advantage in its U.S. House delegation.
