JEFFERSON CITY, Mo. (AP) — The battle for political advantage in state capitols is poised to become more intense after the U.S. Supreme Court decision declaring that federal judges have no role in deciding partisan gerrymandering claims. The ruling Thursday could empower Republicans and Democrats to become even more aggressive in drawing districts to their benefit after the 2020 census. It also could shift legal challenges to state courts and lead to more state ballot measures adopting redistricting reforms.
