US House Redistricting Fuels Partisan Gerrymandering Ahead of Midterms

Recent Supreme Court rulings have weakened key protections of the 1965 Voting Rights Act, making it easier for state legislatures to redraw congressional districts in partisan ways. The court’s decisions in cases such as Louisiana v. Callais and a shadow‑docket ruling for Alabama have opened the door for GOP‑controlled states—including Texas, Louisiana, Ohio, Missouri and Alabama—to redraw maps that could add several Republican seats before the November midterm elections.

Democratic‑led states are also engaging in mid‑decade redistricting. California has passed Proposition 50 to reshape its 52 districts, while a Virginia special election map was struck down by the state Supreme Court. Experts warn that the combined effort could produce a more uniformly partisan House, diluting minority voting strength and reducing overall responsiveness of Congress. Omar Noureldin of Common Cause said the moves “allow politicians to choose their voters,” and David Daley of FairVote warned that by 2028 the national map could become “radically and maximally gerrymandered.”
