Atlantic County voters could see a delay in delivery of sample ballots ahead of the June 4 primary election due to an issue with the digital file meant for printing and distribution of ballots, county officials said Thursday. Officials representing the county Board of Elections worked with the county clerk and superintendent of elections to correct the problem and reduce, but not eliminate, a delay in the ballot mailing deadline, which was noon Wednesday, for the early voting period, county officials said in a news release.
