Our first black president will turn over the White House next month to a man I took to calling the Orange Hindenburg, back when I was sure the candidacy of Donald Trump would crash and burn. I was certain that the political, social, and racial legacy of Barack Obama would be preserved by the so-called Obama coalition: the black and brown voters, backed by some white women and millennials, who had made him president. Instead, that legacy could be obliterated by what pundits are calling a “whitelash”: the unexpected surge of white voters who took their country back from a black man, refused to hand it over to a liberal white woman, and entrusted it instead to a man whose victory has been hailed by white nationalists and the Ku Klux Klan.
