Chapter 13 analyses how profound socio-demographic changes in America have contributed to a shift from the faith-driven culture wars of the twentieth century to a more secular identity politics between liberal cosmopolitans and populist communitarians in the twenty-first century. This trend appears closely linked to the rapid decline of American Christianity, which along with globalisation, individualisation and rapid ethnic change has led to an identity crisis in parts of the white working class. Given the relative unresponsiveness of the traditional party system to this development, Donald Trump succeeded in capitalising on this crisis of identity through a ‘hostile takeover’ of the GOP by the alt-right, and a gradual ‘Europeanisation’ of the American right, which shifted from a faith-based social conservativism to a more identitarian and populist white identity politics.
