There is a national push for states to increase voting security, after evidence that Russia is continuing to try to influence elections. A proposal by the state Election Commission that all voting machines leave a paper trail ended when Republican leaders balked. They argue that local election commissions should decide what is best and point to the significant expense of replacing all voting machines. Democrats and cybersecurity experts have voiced concerns about the lack of paper trail requirements on election machines.
Tennessee is one of 12 states that do not require electronic voting machines to print out hand-marked paper ballots.
That can leave election results vulnerable to untraceable manipulation by hackers. Homeland Security officials have notified election officials in 21 states that their systems have been targeted by Russians. Authorities have since said they believe all states were targeted.
