The North Carolina State Board of Elections has voted to keep 10 polling places open longer beyond their initially scheduled closure because they opened late or had technical difficulties. The move Tuesday is expected to delay statewide reporting of results. The longest extension was 45 minutes for a site in Sampson County. That means the state can’t publicly report any statewide results until 8:15 p.m. State elections officials last week said that if hours are extended at any polls, they wouldn’t publicly post any results until all polls are closed. Also on Tuesday, police in Charlotte said an armed man loitering at a polling site was arrested and charged with trespassing.
