This chapter shows how factional divisions in FECODE shaped electoral mobilization and ideological rigidity. It links the repertoire of leftism to competition among rival factions in internal union elections. Contrary to the Argentine tendency toward ongoing and disruptive protests, protests by FECODE were easier for the government to manage owing to the political priorities of union factions. The next section shows how factionalism and ideological rigidity produced rival negotiating strategies that limited the influence of union leaders on the policy process. The final section shows that leftism remained the central tendency of political mobilization for the union throughout the 2010s.
