Advice given, not followed
Experts and state officials agree that the voting computers the committee selected that are now being used in the 2020 presidential election, called Ballot Marking Devices, or BMDs, are safer than the ones S.C. voters were using before, called Direct Recording Electronic machines, or DREs.In his testimony to the
The machine's software had recurring bugs, Buell noted. From looking at data of years of elections, Buell wrote that he found flaws with the code that led to votes being counted more than once, ignored or tallied incorrectly. Problems with the external hardware became more frequent as the computers got older and also led to votes not being included in official counts, he observed.
More than one problem sometimes happened at a time. On
In his reviews, Buell mentions that he never encountered an error in the ES&S devices so grave that it might have changed the outcome of a state race. But even small mistakes that occur in voting technology can pose a serious threat to democracy, Blaze explained before
"A hostile state actor who can compromise even a handful of county networks might not need to alter any actual votes to create widespread uncertainty about an election outcome's legitimacy," Blaze said. That bad actor could do something as simple as plant a detectable software bug in just a few voting machines or add a couple of fake names to the list of people who voted, he explained.
Then, if the "wrong" candidate wins, "they could covertly reveal evidence that county election systems had been compromised, creating public doubt about whether the election had been 'rigged,'" Blaze told lawmakers. "This could easily impair the ability of the true winner to effectively govern, at least for a period of time."
The BMDs chosen last year by the panel that are being used today are similar to DREs in some ways. Both types of voting computers display or read aloud a ballot electronically, for one. But instead of recording voter selections inside the computer's memory like DREs do, BMDs print out a paper ballot that shows a barcode and text, intended to reflect the choices the voter made on the computer. That ballot is then scanned and recorded through a different device.
Proponents of the system say that because of that print-out, voters can be trained to spot when something goes wrong before their vote is counted, and that software bugs or foreign interference can be identified quicker than with the DREs. Some disability advocates prefer the computers because they allow people with disabilities to vote with accommodations through the same machine that a non-disabled person uses, reducing distinctions between the two experiences.
But scientists say the five-member panel could have picked a safer system.
Not the "gold standard" for SC
Of the seven options submitted to the state in response to its request for proposals (RFP) last year, three vendors proposed the state buy their hand-marked paper ballot systems, also known as optical scan paper ballot technology. The hand-marked technology wasn't just significantly cheaper than the BMDs: It also came enthusiastically reviewed by top scholars.On
The authors were clear about their consensus that simpler, hand-marked paper ballot technology would be better than the more expensive and technically complicated ballot-marking devices.
"We write to urge you to follow the advice of election security experts nationwide, including the
"Our strong recommendation is to reject computerized ballot marking devices (BMDs) as an option for
It's a common misconception that because the BMDs spit out pieces of paper, the paper trail they leave is as reliable as the one left by hand-marked paper ballots, Buell said. What most people don't know, he said, is that when the papers imprinted by BMDs are scanned to record the votes encoded on them, the barcodes transmit the voter selections, not the printed words. Since people can't read the barcodes, "a BMD ballot is absolutely not voter verifiable."
Audits conducted after an election can catch evidence of errors in voting technology by comparing the votes printed on paper ballots to the final votes registered. For audits on BMDs to be effective, however, Buell said that auditors would need to statistically sample not just whether the text on the pieces of paper printed by the machines matched up with the votes that were eventually recorded, but whether the text matched with the information transmitted through the barcodes. Buell doesn't believe sampling like that is being done in
Blaze echoed Buell's points about BMDs in his testimony before
Bottlenecks can lead to long lines and wait times, which are known to discourage people from voting. The form of voter disenfranchisement disproportionately affects communities of Latino and Black voters, research from The Brennan Center, a nonpartisan law and policy institute, shows.
Blaze went on to make the same recommendation the 23 experts had sent a year earlier to S.C. lawmakers. Simple technologies, like optical scan paper ballot technology, should be deployed to make sure elections are as strong as possible against external attacks.
But in the notes scribbled by the five panelists during the meetings they attended to decide which vendor and technology system would win the S.C. award in 2019, the known security problems with BMDs and benefits of hand-marked paper ballots were hardly mentioned. The notes were obtained via an open records request and reviewed by The State newspaper.
"Handmarked systems can cause human error + doesn't provide the necessary assistance for those with disabilities," wrote Amanda Loveday, one of the five, on an evaluation form about one of the hand-marked proposals. About the BMD system proposed by ES&S, she wrote that "ES+S offers customized hardware ... a sophisticated thumbdrive vote secure system." On another form, she added that ES&S's "current relationship + knowledge of the state was a plus." The other selectors made similar remarks.
Ultimately, the group gave the hand-marked systems lower scores and voted unanimously for ES&S's BMDs, which would cost the state over $51 million.
Loveday currently works in public relations and doesn't consider herself "a tech person." Others on the committee included a councilman and two businessmen. Loveday said she did not remember being given academic articles or research from computer scientists as part of the selection process, nor did she remember being shown the letter sent to S.C. lawmakers and the

Teague of the League wasn't surprised when she heard that the committee had decided to select ES&S and its BMD system last year.

Lawmakers, scientists, and citizens repeated similar concerns to The State.

But the success of ES&S and its nearest competitors isn't owing to their technological prowess, suggested Dan Wallach, professor of computer science at
"There's certainly nothing worthy of the phrase 'innovative' from anybody in the entire election space," Wallach said. "To the extent that we've had public analysis of the major current vendors, the code that they wrote for the previous generation of products, it was just really terrible. They were making it up as they went along."
The RFP sent to
Though ES&S receives millions of public dollars to pay for voting technology and services, an ES&S spokeswoman said that the company was too busy preparing for or supporting elections to schedule a tour or call with a reporter from The State when asked in September and October. At the time of publication, ES&S did not choose to comment about the technical experience of the company's employees.
Wallach was frank about the lack of good options on the market. There are federal standards for the technology, but they're "old and inadequate." Even so, the systems available for sale today are not built to the most recent guidelines, Wallach said.
Since mainstream technology companies have largely decided not to compete for the government contracts, and most counties shy away from creating voting technology in-house, if you're a county looking to buy, all you've got are "new crappy things to replace flaky, old crappy things, and it's the same vendor," Wallach said. "The market for voting equipment is dysfunctional."
One of the ways to improve it is with greater industry transparency, he suggested.
"It's not enough to say who wins the election, the loser requires evidence," Wallach said. "The more transparent it is, the more likely that you have enough evidence to convince the loser."
