In this commentary on Kai Bosworth's ‘What Is “Affective Infrastructure”?’, I seek to address some of the issues that he raises about the notion by fleshing it out in relation to the problem of political organisation in general, and to the concrete case of Brazilian far-right politics in particular. This leads to conclusions about the concept's generality, its distinction from similar notions such as ‘affective conditions’, its criteria of individuation and relation to a specific material support, and the conceptual pair potentia–postestas.
