US Supreme Court decisions reshape voting maps, spark civil war concerns

A poll of likely midterm voters found that 57% of Americans think the United States is headed toward a second civil war, and 69% say democracy is under serious threat. The survey follows a string of Supreme Court rulings under Chief Justice John Roberts that have weakened the Voting Rights Act. In Louisiana v. Callais, the Court struck down the state’s 2024 congressional map that created a second majority‑Black district, siding with plaintiff Phillip “Bert” Callais, a self‑described “non‑African‑American voter.” The decision eliminated the “effects test” used to prove discriminatory intent, making future Section 2 challenges much harder. Earlier rulings – Shelby County v. Alabama (2013) and Rucho v. Common Cause (2019) – removed pre‑clearance requirements and declared partisan gerrymandering claims non‑justiciable, respectively. Election‑law experts warn that up to 19 Democratic seats in the Deep South could be lost, potentially consolidating one‑party rule in states such as Tennessee, Alabama, Mississippi, South Carolina, Florida and Louisiana. Representative Bennie Thompson warned the outcome is “equivalent to a second civil war,” while commentators have drawn historical parallels to the 1850s and the Dred Scott decision.

These developments have intensified partisan alarm over voting rights, redistricting and the future of American democratic institutions.
