In The Dark Side of Podemos?, Booth and Baert explain why Schmittian theory resonated with Podemos' founders. In doing so, the authors position Podemos and the ideas that guide it within the context of recent Spanish history and ongoing politics of memory, revealing a story about how personal and political narratives have combined to produce a formidable political force. In this intriguing narrative in political theory, Booth and Baert trace the multi-layered and often surprising connections between the conservative philosophy of the Nazi jurist Carl Schmitt and the progressive populism of Podemos. In the process they consider the analogies between Weimar Germany and contemporary Spain, General Franco's regime and the warm reception for Schmitt's views on power, the political, the "exception", and decisionism. In tracing the connections between the Podemos leadership and Schmitt's critique of liberalism and parliamentary democracy, they also describe the profound crisis within the European Union between Germany and its underdeveloped periphery. A tour de force, the authors develop a compelling historical sociology of ideas and expose the ambiguities of populism as appealing to extreme right and left politics , and simultaneously dissolving this political division.
