With renewed vigor, U.S. top court scrutinizes curbs on voting

Government officials across the United States try to maintain accurate voter rolls by removing people who have died or moved away.The justices will hear arguments in Republican-governed Ohio's appeal of a lower court ruling that blocked its policy of erasing from voter registration lists people who do not regularly cast a ballot.Under the policy, such registration is deleted if the person goes six years without either voting or contacting state voting officials.
