North Carolina's Republican candidate for governor is at the center of a national news story. That's because of the salacious nature of a series of posts by Mark Robinson, unearthed by CNN, from a pornography web site's discussion board.

North Carolina's Republican candidate for governor promised to stay in the race on Thursday after CNN reported that he once called himself a "black NAZI!" and proposed bringing back slavery in comments posted on a pornography website.

The deadline for a candidate to withdraw is midnight tonight, but Lt. Gov. Mark Robinson has vowed to stay in the race.
