Enfranchising emigrants implicitly involves inviting them to have a voice and increasing engagement in home politics, thus maintaining active membership of their nation of origin. However, in the Latin American Southern Cone (as well as in several other countries in the region), both state policies and expats’ responses have fallen short of making that invitation effective. What explains this inclusion paradox? Why, while franchise is expanding has effective political inclusion of citizens living abroad not materialized? This article addresses these questions for the cases of Argentina, Brazil, and Uruguay. Conclusions highlight relatively unexplored explanatory factors and enhance our understanding of the links between migration policy innovation and political inclusion beyond borders in some of the least studied cases in the literature.
