Computerized voting systems in 16 states – including some swing states – have no paper backup ballots or other paper trails "in some or all counties" and so could not reconstitute an accurate vote count from those machines if software or hardware fails, the report says.
Lack of audits – 25 states don’t do them – was another key problem, since paper ballots as a backup aren’t enough to ensure vote integrity.
"The problem is not just fraud and the threat that these systems can be manipulated, but that they are aging, complex systems where things go wrong," says Pamela Smith, president of the Verified Voting Foundation. "What matters most is: Can you recover from problems? Can you recover votes that are counted accurately? There are still way too many systems nationwide that can't do that."
States whose systems lack paper backups for some of or all their voting systems include: Arkansas, Colorado, Delaware, Georgia, Indiana, Kansas, Kentucky, Louisiana, Maryland, Mississippi, New Jersey, Pennsylvania, South Carolina, Tennessee, Texas, and Virginia.
