The present darling of the right wing, Dr. Benjamin Carson, is a distinguished neurosurgeon who went from the depths of Detroit poverty to the heights of Johns Hopkins Hospital in Baltimore. But his current status among conservatives isn’t so much rooted in Carson’s redemptive rise from rags to respectability, as it is in the belief that he is, in the long winter of Obama, the one they’ve been waiting for.

Last week, Carson came under attack for comparing advocates of same-sex marriage with advocates of bestiality and the North American Man/Boy Love Association. He then cast himself as a victim of political correctness, besieged by white liberals — “the most racist people there are” — who could not countenance his heterodoxy and wanted to keep him on the “plantation.”

The plantation metaphor refers to a popular theory on the right. It holds that the 95 percent of African-Americans who voted for a Democratic president are not normal Americans voting their beliefs, but slaves. A corollary to the plantation theory is the legend of the Conservative Black Hope, a lonesome outsider, willing to stare down the party of Obamacare and stand up for the party of voter ID. Does it matter that this abolitionist truth-teller serves at the leisure of an audience that is overwhelmingly white? Not really. Blacks are brainwashed slaves; you can’t expect them to know what’s in their interest.

Benjamin Carson is that Conservative Black Hope of the moment. His rise began with a meandering speech that mixed policy, humor and victimization in February at the National Prayer Breakfast, mere feet from the president of the United States, who was forced to take his medicine in a way that Clint Eastwood could only dream of. When Sean Hannity interviewed Carson about his speech he dispensed with the policy and simply dubbed the segment “Lecturing Obama.”
