In Tampa, Florida, the threat of material destruction and social dislocation associated with planned highway expansion has ignited local resistance, which, in turn, brings together a loose grouping of social and political actors. Through a shared commitment to cynicism, the members of this socioeconomically diverse array of antihighway activists join one another in making claims on the state, even as they doubt these claims will ever be heeded. Cynicism, in this context, acts as an affective boundary object that enables actors to negotiate the moments of intrasubjective and intersubjective incoherence that inevitably arise in the course of private and public life. Attending to the citizen effects of cynical affects invites a reformulation of the place of negative feelings within the politics of the city, and social life more broadly.
