Adam Gopnik revisits two famous American essays from the 1960s and finds a remarkably contemporary vision - and one 'that seems to have an application to our own time and its evident crisis.'

He couples Richard Hofstadter's 1964 essay, 'The Paranoid Style in American Politics' with Daniel Boorstin's 1962 classic on 'image' and America's tenuous relationship with facts.

'It is the admixture of Hofstadter's political paranoia with Boorstin's cult of publicity,' writes Adam, 'that makes Trump so very different from previous political figures.'
