How Trump Thinks

The most unusual feature of **Donald Trump's** nationalist and populist campaign for the presidency of the USA was his **obsessive use of Twitter**. Like other social media, this form of communication has often been assumed to encourage the dissemination of liberal values and the circulation of facts. Trump's tweets, by contrast, formed a constant stream of provocations, insults, conspiracy theories, 'alternative facts' and outright lies. **And they helped him win power**. **Peter Oborne** , author of *The Rise of Political Lying* and *Not The Chilcot Report* , analyses Trump's incendiary mendacity in all its bewildering guises, and shows how this fusion of entertainment and cunningly crafted propaganda has **destabilized the world's most powerful democracy**.
