It's unlikely that we can get this passed in 2018, but a Democratic majority could very well do this next year. Via Ars Technica:

A bipartisan group of six senators has introduced legislation that would take a huge step toward securing elections in the United States. Called the Secure Elections Act, the bill aims to eliminate insecure paperless voting machines from American elections while promoting routine audits that would dramatically reduce the danger of interference from foreign governments.

The legislation comes on the heels of the contentious 2016 election. Post-election investigation hasn't turned up any evidence that foreign governments actually altered any votes. However, we do know that Russians were probing American voting systems ahead of the 2016 election, laying groundwork for what could have become a direct attack on American democracy.

"With the 2018 elections just around the corner, Russia will be back to interfere again," said co-sponsor Sen. Kamala Harris (D-Calif.).

So a group of senators led by James Lankford (R-Okla.) wants to shore up the security of American voting systems ahead of the 2018 and 2020 elections. And the senators have focused on two major changes that have broad support from voting security experts.

The bill proposed to get rid of paperless electronic voting machines, which are vulnerable to hacking and can't be accurately audited.The Secure Elections Act funds the replacement of these systems by the states.

The act would also encourage states to perform routine post-election audits based on modern statistical techniques.
