evidence: (CNN) — Mark Robinson, the controversial and socially conservative Republican nominee for governor of North Carolina, made a series of inflammatory comments on a pornography website’s message board more than a decade ago, in which he referred to himself as a "black NAZI!" and expressed support for reinstating slavery, a CNN KFile investigation found. [...] CNN’s reporting on Robinson’s comments comes a few weeks after The Assembly, a North Carolina digital publication, reported that Robinson frequented local video pornography shops in the 1990s and 2000s. The story cited six people who interacted and saw him frequent the stores in Greensboro, North Carolina. A spokesperson for Robinson called the story false and a "complete fiction." [...] In March 2012, Robinson wrote that he preferred the former leader of Nazi Germany Adolf Hitler over the leadership in Washington during the administration of Barack Obama.
