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.
"I'm amazed so many states do not have paper backups for their equipment," says Joanne Rajoppi, clerk of Union County, N.J., and the incoming president of the International Association of Clerks, Recorders, Election Officials, and Treasurers, a volunteer organization. "We have paper backup in New Jersey. If there's a challenge to show where your votes come from, you're going to have to prove it. It's only fair."
At the same time, 31 states have adopted new Internet-based systems intended to allow troops and other citizens abroad to transmit their vote home electronically. But while six of those states place some security restrictions on how completed ballots can be returned, 24 states permit electronic votes to be returned "without restrictions," thus running the risk of ballots being intercepted and altered, the study says.
