Populism is not a fad or an epiphenomenon. As the election results prove, populism is increasing almost all over the world, and populists rule the four most crowed democracies. Populist parties are gaining ground in the majority of the EU countries and in the two latest American presidential elections two populists – Donald Trump and Bolsonaro – achieved the power stage of the USA and Brazil. In the European Union, after a long period, while populist parties assumed an anti-system position, most of the populists changed their strategy trying to reach the power, and they are already the third political force. This increase has been constant. However, the economic recession and the large flow of refugees and immigrants were at the roof of the most recent rise. The essay analyses the populist parties’ strategic change and the reaction of the mainstream parties. It also explains that right-wing populism is using the nationalist rhetoric and some policies of social democracy into the service of nationalism, and it is increasing faster than the left-wing one. Moreover, the essay shows that populist governments stay in power longer than non-populists do. Finally, it proves that the populist discourse works as a new siren song because populist leaders say what the citizens are keen to hear.
