So it’s back to basics for a man whose political career, let us remember, was based on the lie of birtherism — the conspiracy theory, constantly promoted by Trump, that Obama was born in Africa and never legitimately elected.

Harvard historian Henry Louis Gates nailed it in a PBS documentary. “There was a shocking amount of resentment that a black family had been in the White House for two terms,” he said. “I think it would be naive to overlook it — the irony that one of the legacies of Obama’s presidency was an enormous amount of resentment.”

Sadly, it never takes much to stoke the embers of racial resentment and hatred in this country. But that is Trump’s strategy. He’s playing the race card because he’s holding a weak political hand.
