“It would be terrific to see the focus on election security lead to more investments in better, more trustworthy systems,” said Mark Lindeman, co-director of Verified Voting, a nonpartisan election security organization. The gold standard for voting security is hand-marked paper ballots, according to security experts. That’s because a paper ballot eliminates the risk of technical difficulties or certain kinds of malicious acts (think hacking) that could change or destroy your vote, and any concerns can be addressed with a recount. Because of that, most states currently use hand-marked paper ballots or have voting machines that generate paper records for verification. But in six states — Indiana, Louisiana, Mississippi, New Jersey, Tennessee and Texas — some or all voters still cast ballots on machines that have no paper record whatsoever, according to data from Verified Voting. While there’s no evidence that these machines have ever been hacked during an election, it’s technically possible, and they’re also prone to all kinds of undesirable malfunctions, including losing votes. With no paper backup to audit, these machines are the kind of election security liability that politicians say they’re invested in fixing.
