Gov. Tom Wolf announced Dec. 31 that all 67 Pennsylvania counties have taken official action toward acquiring new voting systems.

According to a statement from the Wolf administration, the U.S. Department of Homeland Security and other national security and election security experts have urged Pennsylvania and other states to use new voting systems with advanced security and a paper trail.

"This is a tremendous accomplishment, and I applaud all 67 counties for their commitment to protecting our elections," Wolf said. "These new modern machines are an important step to strengthen the accuracy of our voting systems and the integrity of our elections."

Every new system has successfully completed penetration testing, access control testing and testing to ensure that every access point and all software and firmware are protected from tampering, the administration said. In addition, every voting system and paper ballot must include plain text that voters can read to confirm their choices before casting their ballot and election officials can use to perform preelection testing and post-election audits and recounts.

Counties were required to take action toward selecting new voting systems by Dec. 31, 2019, and implement the new systems no later than the 2020 primary election. Forty-five counties used new systems in the 2019 general election in November.
