Mail-in absentee ballots in North Carolina would have to be received by the day of the election, under a Republican-backed bill that has cleared a divided Senate committee. Current law says ballot envelopes must be postmarked by the election date and received within three days to be counted. A bill sponsor says setting the receipt deadline at 5 p.m. on Election Day or on the statewide primary election date will improve the public’s confidence in election results. But Democrats say that would cause many lawfully cast ballots to be tossed due to mail carrier delays and would cause voters to be confused about when they should mail in their ballot.
