Though international Disinformation campaigns have targeted the 2022 United States midterm elections to a degree, a lot of the strain on US voting infrastructure has come from inside the home. Violent domestic threats against election officials have soared across the nation up to now couple of years, endangering staff and, more and more, driving them from the occupation altogether. And as early voting started across the US in current days, scattered incidents at poll drop bins and polling locations have put voters on edge. Last week, a federal choose in Arizona notably ordered armed members of a bunch known as Clean Elections USA to cease visibly carrying weapons and sporting physique armor inside 250 toes of poll drop bins.

Officials and researchers say that casting a poll shall be secure and uneventful for the overwhelming majority of US voters. They additionally emphasize, as was the case in 2020, that US elections are in reality probably the most secure and rigorous they’ve ever been due to numerous initiatives, together with efforts to section out voting machines that don’t produce a paper backup and the expanded use of postelection audits, together with gold normal “risk-limiting” audits. Yet erosion of public trust in any election system is as big a threat to the democracy it underpins as real-world meddling. With so much at stake, the 2022 US midterms are highlighting the criticality of one core US voting protection: the secret ballot.

“The secret ballot is really profound—it’s critical to capturing the true will of the people,” says Ben Adida, the executive director of VotingWorks, a nonprofit maker of open source voting equipment. “People who would break your kneecaps or physically threaten you at the polls represent one extreme, but there are also much more subtle ways that undue influence could affect the outcome of an election. Think about people who support a candidate but don’t feel that strongly about it. They might think, ‘Well, do I really want to fight with my spouse or my employer? It’s just one vote.’”

Until the 1890s, US voting was a local, public event, conducted either orally or using paper tickets. And efforts to institute private voting using the now-familiar “Australian ballot” method were controversial at first because the spectacle and transparency of public voting were embedded in US democratic culture. 

Being able to cast your vote secretly, though, provides two core democratic protections. The first and perhaps more intuitive benefit relates to individual privacy. Whether using a voting machine or filling out a scannable form, US voters cast their ballots at the polls in privacy booths. And while they must be registered to vote in databases that are often public, the votes they actually cast are totally disconnected from their identities. This means that even if a family member, acquaintance, or political operative is voting with you at the same time, they shouldn’t be able to actually know for sure how you voted, leaving you the opportunity to vote however you choose.

“There’s a challenge when you can’t connect the vote to the person, but we’ve largely solved that problem with audits after elections and checking that we’re recording votes accurately,” says Lawrence Norden, senior director of the elections and authorities program on the Brennan Center at New York University School of Law. “For a majority of American history, elections were held in public, and there was a reason we moved to the secret ballot. Part of it was that people were subject to violence and intimidation, and actually polling places could become violent.”
