“This is Martin Luther King on steroids,” Donald Trump told a crowd in Greensboro, North Carolina, three days before Super Tuesday. Mark Robinson, the lieutenant-governor and Republican candidate for governor whom Mr Trump was endorsing, wasn’t sure he liked that, the former president went on to say.

Writing on Nude Africa, a porn site, he called himself a “black NAZI”, said he wasn’t in the Ku Klux Klan because “they don’t let blacks join” and that if they brought back slavery, which he wished they would, he would “certainly buy a few”.
