Jeff Mordock and Dan Boylan write for the Washington Times about continuing concerns surrounding outside interference in American midterm elections.

Just a day before an estimated 100 million voters across the country cast ballots in the midterm elections, experts remain[ed] tense and concerned about the risk of foreign interference, vote hacking and fraud, in what they say is shaping up as a test of historic proportions for the integrity of America’s electoral systems.

Tuesday’s vote is seen as being critical to the remainder of President Trump’s time in office, and a measure of what U.S. officials have learned since the widespread problems of two years ago.

It is also the first major election since the Kremlin in 2016 engaged in what Department of Homeland Security cybersecurity official Jeanette Manfra told Congress was “a brazen, multifaceted influence campaign aimed at undermining public faith in our democratic process, generally and our election specifically.”
