As primaries ramp up in states across the U.S., concerns about election cybersecurity are mounting too. This week, a group of Democratic senators introduced a bill to mitigate some of the well-established risks that the nation’s uneven mix of voting machines and election systems poses.

The new bill, known as the Protecting American Votes and Elections Act, proposes two significant measures. First, because not all digital voting systems produce a paper trail, it would require all state and local elections to ensure that their equipment produces voter-verified paper ballots that can be cross-referenced. Second, for all federal elections regardless of outcome, state and local governments would be required to conduct audits comparing digital ballots to a random selection of paper ballots. The latter policy would cover the 22 states that currently don’t require audits following elections.
