Milwaukee audit logs show no evidence of election fraud, experts say

Conspiracy theories circulated after the Milwaukee error in August, but logs of what happened reveal nothing askew.

It took mere minutes for conspiracy theorists to seize on a Milwaukee election error after the August primary, when officials initially forgot to extract election results from five of the city’s nine absentee ballot tabulators. They lobbed baseless accusations that election officials had switched votes or otherwise tampered with the results.

But audit logs from those five tabulators show no evidence of tampering between the time officials initially left the facility and returned again to correctly extract results, experts told Votebeat.

“I don’t see a ‘there’ there,” said Duncan Buell, a chair emeritus of computer science and engineering at the University of South Carolina who has been analyzing election data and voting systems since 2010.

Ryan Macias, an election consultant who previously worked for the arm of the Election Assistance Commission that certifies voting machines, agreed there were “no signs or evidence that anything was done outside the norm” between the initial error and the successful extraction of the results.

More than three weeks after the primary election, city officials released audit logs from all nine tabulators to the Wisconsin Election Commission and the public on Sept. 4. The files detail every action on the nine Milwaukee tabulators used to count absentee ballots for the Aug. 11 election.

On each of the five affected tabulators, the logs tell the same story: Officials mistakenly selected “export audit log” instead of “export files” during the initial extraction, which happened between 10:15 p.m. and about 10:40 p.m. Then, officials locked the machines.

Officials began turning the machines back on at around 11:30 p.m., after they realized they had made a mistake. They extracted the correct files shortly after midnight. The audit logs show no ballots being scanned, votes being deleted, or that the data contained on the tabulators was manipulated in any way.

The error didn’t change the vote count at all. It just delayed election results by a couple hours.

When Macias first learned of the issue, he assumed that the problem was human error and would be resolved.

“Now, looking at the audit log, I can tell you with a 100% fact that what I assumed happened [is what] happened,” he said.

Other experts agreed.

Jennifer Morrell, CEO of The Elections Group, said she reviewed the audit logs with her team of experienced election experts.

“From what I see, those logs match the public account exactly,” she said.

“In the roughly two hours between those two exports, there’s no scanning or counting activity recorded in the logs on any of those five machines,” she said. “And just as importantly, the ballot counts on every machine match the officially reported.”

Conspiracy theories percolated well before Milwaukee released audit logs

Conspiracy theories about what may have transpired in Milwaukee on Election Day began circulating almost immediately after Milwaukee officials announced the mistake. Popular social media accounts questioned the credibility of election officials and others suggested that officials were directly involved in fraud.

Three days after the election, Votebeat requested the audit logs — the records that could show exactly what happened on the tabulators during the period conspiracy theorists were questioning. Milwaukee did not release them until Sept. 4, more than three weeks later, and after the Wisconsin Elections Commission also asked the city to make them public.

Experts said that delay was not unusual.

“Releasing audit logs — these machine logs — that’s not a typical part of the documentation that election offices normally produce,” Morrell said, adding that it’s likely that Milwaukee would have needed legal approval before releasing the logs. “The fact that they did make them public, I think that’s a responsible process — not a cover up.”

More important, she said, is that the officials retained the records in the first place.

“The fact that the log is there, the fact that these things are recorded should be seen as a positive even though it was slow for them,” she said. “I think the more concerning thing would be if the log just didn’t exist at all.”

Milwaukee plans better documentation for the future

In response to the error, Milwaukee election chief Paulina Gutiérrez outlined several changes meant to prevent similar problems.

Written instructions for extracting results will now include images showing election officials which options to select on screen, Gutiérrez said in a letter to the Wisconsin Elections Commission. Those instructions will also be made available to observers at the city’s absentee ballot facility.

Before the results are downloaded, she said, the extraction teams will be briefed on the process. As workers move through the steps, they will verbally identify each selection they make so other members of the team can confirm they have followed the correct procedure.

“In this instance, an error occurred during the results-download process,” she told the commission. “At the same time, the safeguards surrounding the election worked as intended: the discrepancy was identified, the underlying election results remained intact, the correct files were retrieved, and Milwaukee’s accurate election results were ultimately reported.”
