WaPo:

Election security is already emerging as a key talking point on the campaign trail as Democrats offer up policies to secure votes from potential tampering and tout their own cybersecurity records — a sign they think this could be a strong wedge issue against President Trump. 

Once-wonky security proposals are now applause lines with voters. Take Sen. Kamala Harris (D-Calif..), who made a shift to paper ballots a key talking point at a breakfast this week in New Hampshire: “Going back to the future, the best and smartest way to conduct voting: paper ballots. Because Russia can’t hack a piece of paper.” The crowd erupted in approval.

And Sen. Amy Klobuchar (D-Minn.) made the case for upgrading voting machines at a town hall in New Hampshire this week: Cyber “is the next arena for warfare. We’re already seeing it right now,” she said. “And just to give you an example, the bill that I had to upgrade our election equipment cost literally — bipartisan bill — 3 percent of one aircraft carrier.” In fact, all six U.S. senators that threw their hats in the ring for the Democratic nomination have co-sponsored bills aimed at protecting election systems against Russian hackers.
