The Supreme Court sided Friday with Ohio's top elections official in a dispute with the state Republican Party over voter registrations.
The justices overruled a federal appeals court that had ordered Ohio's top elections official to do more to help counties verify voter eligibility.
Secretary of State Jennifer Brunner, a Democrat, faced a deadline of Friday to set up a system to provide local officials with names of newly registered voters whose driver's license numbers or Social Security numbers on voter registration forms don't match records in other government databases.
Ohio Republicans contended the information for counties would help prevent fraud. Brunner said the GOP is trying to disenfranchise voters.
