Civitas suit: Verify addresses on all one-stop votes

Francis De Luca, president of the nonprofit, acknowledges that the challenge is unlikely to change the outcome of any races.

"Even if they follow what we are requesting, the results aren't going to change in most of the races," De Luca said.

The Civitas suit throws another wrinkle into what is already a complex election landscape. De Luca and his group have complained about same-day registration for years, saying it opens the state up to voter fraud.

"We think it's important to create a record about the chaos and turmoil same-day registration brings to the election process," he said.

Voter rights advocacy groups say that it gives many people, particularly young and poor individuals, an opportunity to vote.

"To count ballots without verification of same-day registration information discriminates by treating one class of voters differently from another," said De Luca. "The State Board of Elections should examine every ballot cast via same-day registration to verify that every vote cast is genuine and legitimate."

Attorney Marc Ellis, who works for Cooper's campaign, released a statement Tuesday afternoon in response to the lawsuit.

"Since losing on Election Day, Gov. McCrory has sought to undermine the results of this election. Republican-controlled boards of elections have overwhelmingly dismissed the McCrory campaign’s baseless complaints," the statement said. "Today’s lawsuit by Civitas is just the latest effort to disenfranchise legally registered voters. Instead of attacking North Carolina voters and undermining our democratic process, Gov. McCrory needs to accept his defeat and concede."
