And on Sunday, Robinson returned to where he started his campaign: Ace Speedway in Elon. Michelle Morrow, the GOP candidate for superintendent of public instruction, and Chad Brown, who is running for secretary of state, joined him at the racetrack in front of a sparse crowd.

The scene was in stark contrast to the scene 18 months ago, when many of the state's most elected Republicans attended the opening of his campaign and spoke on his behalf. Many have since backed away from the candidate after a CNN investigation published in September found that an account associated with Robinson made a series of explicitly racist and sexist comments on a pornography website.

The few speakers at Sunday's event defended Robinson's character in the face of controversy, but also repeatedly reminded supporters that a vote for him and other GOP candidates, regardless of their personalities, was first and foremost a vote for conservative policymaking. One such memory came from Robinson himself.

“You go and vote for policies, not people, not personalities,” Robinson said. “You don't make decisions based on what someone's political opponent said about them in an ad. They do it based on what these people have done in office.”

Robinson says he will accept Tuesday's results, win or lose.

Robinson told NC Newsline on Sunday that he would accept the results of Tuesday's contest, regardless of the outcome.

“Yeah, that goes without saying,” Robinson said. “We are willing to accept the results of the election, win or lose, and if it is a tie, we are willing to resolve it however we can legally resolve it.”
