The North Carolina Republican Party is facing one of the most predictable crises in the history of party politics.

Its primary voters enthusiastically supported a candidate for governor named Mark Robinson — voting for him by a more than 45-point margin over his closest rival (he won by 64.8 percent to 19.2 percent) — even though he had a remarkable record of deeply inflammatory and even unhinged statements.

Last week, a comprehensive CNN report unearthed compelling evidence that Robinson had posted on a porn site called Nude Africa. I cannot possibly repeat the worst posts, but the less graphically obscene ones included statements like this: “I’m a Black Nazi,” and “Slavery is not bad. Some people need to be slaves. I wish they would bring it back. I would certainly buy a few.”

That’s not all. “I’m not in the K.K.K.,” he also said, according to the CNN report. “They don’t let Blacks join. If I was in the K.K.K. I would have called him Martin Lucifer Koon!” He said he’d prefer Hitler to what he sees in Washington today.

No one, however, should be surprised. Even before the primary, Robinson’s horrific character was on display. Among other things, he had called school shooting survivors who advocated gun control “media prosti-tots,” accused Michelle Obama of being a man, and trafficked in so many antisemitic tropes that his election as lieutenant governor in 2020 was an alarm bell for Jewish leaders in the state.

In other words, Republican voters knew he was a bad man when they chose him. Now they know he is a very bad man.
