“BREXIT-plus-plus-plus” was how Donald Trump—who also called himself “Mr Brexit”—termed his pitch to voters during his successful presidential campaign. Sure enough, many Americans will soon be waking up soon to a feeling similar to the one Remainers in Britain experienced on the morning of June 24th: bafflement at the failure of so many polls to predict the result, shock at the electorate’s defiance of expert opinion, concern for liberal values. If Mr Trump relishes the comparisons it is because he identifies with the architects of Britain’s departure from the European Union: like him, privileged demagogues deft at manipulating the public’s worst fears and instincts.
