The book presents an overall diagnosis of liberal democracy and traces the emergence of a new political system that is becoming the political dominant in the contemporary world.
It is a system that is emerging from the crisis of liberal democracy - retaining some of its elements, transforming others, and introducing others. Metapopulist democracy builds on the theory of interregnum as presented in The Age of Transition, incorporating new concepts that place politics in a broader economic, social and cultural context.

It elucidates political strategies that make it possible to unite a fragmented society without coherent doctrines and ideologies. It explains why today's politics is full of contradictions and logical incoherences.It asks how to respond to metapopulist politics and how to create an emancipatory politics that leads beyond the interregnum.
