This chapter examines how social position and everyday experience shape political commitment within Mexico City’s working-class districts. Focusing on the borough of Iztapalapa, it argues that living in a politicised environment does not automatically translate into sustained activism. Through the trajectory of Sandra, a low-level public employee, the analysis explores how ambivalent forms of engagement emerge at the intersection of class, gender, and workplace dynamics. Sandra’s encounters with everyday racism and her aspirations for social mobility reveal that persistence in the movement depended less on López Obrador’s leadership than on local relationships and personal circumstances. Her interactions with neighbourhood leaders such as Isidro exemplify how informal networks and moral economies of reciprocity mediate individual participation. The chapter shows that supporters experienced López Obrador’s discourse not as abstract ideology but as embodied social practice, negotiated through the contradictions of daily life. By tracing these ambivalences, it offers a sociological perspective on the gap between political ideals and lived realities, highlighting how commitment fluctuates within specific social and institutional contexts.
