With Dauphin County’s decision this week to end its standoff with the state and buy new voting machines, all 67 Pennsylvania counties met the year-end deadline to comply with a state order that they implement election systems capable of leaving a paper trail of votes that can be manually audited and recounted. Experts say this is a major step for election security ahead of the November presidential election, ensuring ballots can be accurately tallied even in the face of a cyber attack or a mishap. “The shift from paperless [electronic] machines to having individual paper ballots is a sea change,” said Christopher R. Deluzio, policy director of the University of Pittsburgh Institute for Cyber Law, Policy, and Security. “It’s great, it’s huge, it was necessary.” As recently as 2018, most voters in Pennsylvania used paperless machines that recorded votes in electronic memory. In addition to concerns that computers can be hacked, electronic systems can fail and wipe out all records of votes cast. In April 2018, Gov. Tom Wolf ordered every county to select paper-based machines and implement them in time for the April 28, 2020, presidential primary. Dauphin County, after a weeks-long game of chicken with the state, selected its new systems Monday. The machines will cost $120 million to implement in 58 counties, according to data provided by the Pennsylvania Department of State, with no details available for the other nine counties. Not all contracts are finalized, and the figure does not include increased operating costs over the life of the machines.
