Mark Robinson, North Carolina's Republican gubernatorial candidate, released a statement Thursday denying damning allegations reported by CNN.

Yesterday was the final day to withdraw from the race before ballots are printed, The Raleigh News & Observer said. So "Republicans now appear to be stuck with Robinson," The Atlantic's Graham said. "They can't say they weren't warned."

The CNN KFile investigation cited comments made on a pornography forum for the website Nude Africa under the name "Minisoldr." Details reportedly linked the profile to Mark Robinson.
