Nine months into the Donald Trump administration, the United States seems eons removed from the country that just nine years ago elected its first black president.

Yet the racial divide that Trump demonstrated with his narrow Electoral College win was always there.

President Barack Obama read to a certain portion of white America as an unending attack on white Christian identity, centrality and cultural relevance. In their minds, he was seeking to end their right to bear arms and the right of conservatives to speak freely.

For this group of Americans, Trump has been the corrective. As Ta-Nehisi Coates points out in his brilliant Atlantic essay, “The First White President,” for Trump’s supporters, his election was itself the point. Putting a human wrecking ball against political correctness, feminism, multiculturalism and even decency was the ballgame.

Obama’s election masked this fierce racial schism for only a few short months. That ended the moment he declared, in July of his first year in the Oval Office, that a white Cambridge police officer acted “stupidly” for arresting a black college professor — and long-time Obama friend and mentor — outside his own home.
