FIRST, an apology, or rather a regret: The Economist would prefer not to advertise the rantings of racists and cranks. Unfortunately, and somewhat astonishingly, the Alt-Right—the misleading name for a ragtag but consistently repulsive movement that hitherto has flourished only on the internet—has insinuated itself, unignorably, into American politics. That grim achievement points to the reverse sway now held by the margins, of both ideology and the media, over the mainstream. It also reflects the indiscriminate cynicism of Donald Trump’s campaign.
