"What we have to do is move this state forward because the issues that really matter, public schools, the strength of the economy, our health care system, public safety.

North Carolina general election: | Who are the candidates for NC statewide races?
Robinson has faced some controversy in his bid for the governor's office.
He is suing CNN for defamation.
A CNN story claimed that Robinson made several inflammatory comments on a message board of a pornography website more than a decade ago.
ABC News has not confirmed the reporting and Robinson has denied the claims.
After the story was published, half of his staffers resigned from the job.
ABC11 reached out to Robinson to speak about the campaign and was told he wasn't available during the day.
Campaign volunteer Robert Burns shared his thoughts on Robinson's run.
"Cross your fingers and hope that everything works," said Burns. "I'm optimistic. I don't know how some of these stories and stuff are going to play, but ultimately I think Mark ran a good campaign."
