An Election Day paper shortage in one Pennsylvania county that led poll workers to turn away some voters is now under investigation.

The Luzerne County Board of Elections and Registration asked the district attorney Monday to look into why dozens of precincts ran out of ballot paper. The shortage led to voting delays at the affected polling places, voters being turned away, and an emergency court order to keep polls open until 10 p.m. — two hours after they usually close — to give voters who were previously denied access to the ballot a second chance.

One week later, the cause of the shortage is still unclear. At a meeting of the Board of Elections Monday night, board members offered no new details despite pleas from dozens of residents during a public comment period that lasted well over an hour.

“As a first-time judge of elections, I was appalled, disheartened, and embarrassed on Election Day,” said a woman who identified herself as the judge of elections at a precinct that ran out of paper. “Tell me how we ran out of paper for the polls? Someone definitely failed to do their job.”

Acting Director of Elections Beth Gilbert McBride was not present at the meeting, nor were any staff from the elections office, who normally attend. Gilbert McBride was put in charge of the election in August, shortly after the resignation of the previous director, Michael Susek, and one month after the county had hired her as deputy director.
