These experts said that all 50 states will need to do a major overhaul to avoid catastrophe when President Donald Trump faces off against presumptive Democratic nominee Joe Biden this November. Congress recently passed $400 million in federal grants for states to accommodate the virus in the general election. But Democrats and Republicans have remained split on how to tweak voting rules.

“At all costs, the election must go on,” presidential historian Douglas Brinkley told CNN. “This is not the NBA season or the Olympics."

How to do that involves a host of challenges that make pre-coronavirus election security concerns seem easy by comparison, as The Washington Post reports.

University of Southern California’s Election Security Initiative, which is conducting virtual training for campaign and election officials in all 50 states, told the Post that election officials working remotely could fall prey to Russian hackers. Bad actors could disseminate false rumors about COVID-19 at polling locations to keep voters at home. Or they could spread “fake news” about the elections being postponed or canceled.

Adam Clayton Powell III, executive director of the Google-funded initiative, told the Post, “Security concerns now are more urgent in almost all cases because the virus has really exacerbated security issues.” Steps now being taken include bracing for far more absentee ballots and, for voters who do come to the polls, hiring younger, less vulnerable workers, as well as providing them with enough protective equipment.

Information assurance is crucial to electoral integrity, according to Travis Johnson, the cybersecurity program manager at cloud solutions provider HumanTouch. In an op-ed for the nonprofit AFCEA International, Johnson writes, “To truly ensure the principle of one person, one vote, the American electoral infrastructure should adopt security protocols similar to those used in the cybersecurity industry.”
