"CONSIDER how far Donald Trump is estranged from fact. He inhabits a fantastical realm where Barack Obama’s birth certificate was faked, the president founded Islamic State (IS), the Clintons are killers and the father of a rival was with Lee Harvey Oswald before he shot John F. Kennedy. 

Mr Trump is the leading exponent of “post-truth” politics—a reliance on assertions that “feel true” but have no basis in fact. His brazenness is not punished, but taken as evidence of his willingness to stand up to elite power. And he is not alone. Members of Poland’s government assert that a previous president, who died in a plane crash, was assassinated by Russia. Turkish politicians claim the perpetrators of the recent bungled coup were acting on orders issued by the CIA. The successful campaign for Britain to leave the European Union warned of the hordes of immigrants that would result from Turkey’s imminent accession to the union."
