By Roskell's definition, Trump is the antithesis of charismatic. Thousands of people - from all points of the political spectrum - have already written about, discussed, and analyzed his charisma. Even Trump himself marvelled at the blind devotion of his followers. But Richard Roskell doesn't believe them.

Even more thousands have described a certain middle-European leader from 80 years ago as charismatic; books and academic papers have been written about it, documentaries have highlighted it. None of them, so far as I'm aware, claimed his mass appeal was rooted in innate personal attractiveness or charm. But Richard Roskell insists attractiveness or charm are essential to charisma.

Richard Roskell doesn't back down, no matter how precarious the ledge he's walked himself out on.
