An error by a company that prints ballots for several Pennsylvania counties made thousands of mail-in ballots unreadable Tuesday as voters were deciding hotly contested primaries for governor and U.S. Senate in one of the nation’s most important battleground states.
Officials in Lancaster County, the state’s sixth most populous, said the problem involved at least 21,000 mailed ballots, only a third of which were scanning properly. The glitch will force election workers to redo ballots that can’t be read by the machine, a laborious process expected to take several days. Officials in the GOP-controlled county pledged that all the ballots will be counted eventually.
