The measures upheld include a change to the state’s voter ID law that removes the option for someone to sign an affidavit affirming their identity if they don’t present a photo identification at the polls.
The other measures prevent anyone other than voters from being within 100 feet of a polling place, require an absentee voter’s signature on a ballot to match the signature on their voter registration application, and move up the deadline for voters to return absentee ballots in person.
For anyone this benefits:
