Four years have passed since the 2016 presidential election when revelations of Russian hacking of the DNC threw political contests into turmoil. In the aftermath, the Mueller investigation, Justice Department indictments and other efforts made clear that the US election and voting systems themselves were the targets of cyberattacks. The subsequent Mueller probe and DOJ indictments also revealed massive Russian digital disinformation campaigns that permeated the election.
Now, as the country heads into the next presidential campaign weakened by a pandemic and laboring under a collapsed economy, little has happened over the past four years to substantially shore up voting, campaign or election security, with only marginal improvements made around the edges. There is time, though, to implement last-minute security measures that could substantially improve election integrity, experts say.
