National Association of Counties — The National Vote at Home Institute is a nonpartisan group that works to increase voter access to voting-by-mail. The nonprofit’s executive director, Barbara Smith Warner, said the addition of signature verification in North Carolina would be “a solution in search of a problem.”

“It crosses the line from voter security to voter suppression, I would argue,” Smith Warner said. “We are big believers in signature verification as an organization, but that’s not what this is. North Carolina, they already have multiple layers of security and the idea of this giving more security is pretty head-scratching.”

The National Vote at Home Institute suggests using a variety of signatures the state has access to from the voter over time, including potentially a driver’s license or marriage certificate, as a “best practice” for signature verification, according to Smith Warner.
