Populism differs depending on whether it is described in London or Ankara, in Budapest or Sofia, in Paris or Washington. National history, political institutions and sociology all influence and affect its variations. Some forms are still compatible with liberal democracies, others are on the brink of turning into authoritarian regimes. Beyond these differences, however, there is a common foundation to be found in every situation: frustrations, fears and rejection of the elites. Is this a depressing thought? Not really, because there is some good news to be found herein: barricades – albeit fragile – persevere against hate-fuelled excesses, even in countries where we feared they no longer existed.
