Set against theoretical and strategic debates about theories of radical democracy, left populism and the commons, this article analyses and evaluates everyday struggles in Greek politics after the global financial crisis. It focusses on the cases of Vio.Me – the first workers’ recuperated factory in Greece – and the Metropolitan Community Clinic at Helliniko, which is the largest social solidarity health clinic in Greece. Viewed from the perspective of commoning practices, the article identifies the logics that sustain the beliefs, values, infrastructures and institutions developed at an everyday grassroots level, finding traces of an incipient radical democratic ethos and rationality at work. The new initiatives highlight crucial and often neglected organisational, prefiguring and subjective prerequisites for radical democracy, while challenging elements of left populist political strategy. Our evolving perspective also problematises their political limitations and strategic dilemmas as they struggle to constitute a viable hegemonic alternative to neoliberal rationalities and governance.
