Mr. Robinson, the Republican nominee for governor of North Carolina, vowed to stay in the race and sought to deny the report, which also said he had defended slavery in online posts years ago.

A series of revelations that Republican Mark Robinson allegedly called himself a “Black Nazi” and a “perv” on a pornographic chat site were only the tip of the iceberg, more of his postings have made clear.
