WASHINGTON (AP) — Pennsylvania’s message was clear: The state was taking a big step to keep its elections from being hacked in 2020. Last April, its top election official told counties they had to update their systems. So far, nearly 60% have taken action, with $14.15 million of mostly federal funds helping counties buy brand-new electoral systems.

But there’s a problem: Many of these new systems still run on old software that will soon be outdated and more vulnerable to hackers.

Voting machine maker ES&S has said it “will no longer sell” paperless voting machines as the primary device for casting ballots in a jurisdiction.

ES&S chief executive Tom Burt confirmed the news in an op-ed.

TechCrunch understands the decision was made around the time that four senior Democratic lawmakers demanded to know why ES&S, and two other major voting machine makers, were still selling decade-old machines known to contain security flaws.

Daniel Savickas, who lobbies Congress on election-related issues for the conservative FreedomWorks, blasted the Senate majority leader for letting legislation languish: “Unfortunately, all Senator McConnell wants to do is judges these days,” he said.

FreedomWorks has advocated a more limited federal footprint, but Mr. Savickas said that “there is a role for Congress” to provide money for states to transition to paper ballot backups and to conduct “risk-limiting audits” after elections.
