Thousands of Latin Americans migrate to the United States every year. This article seeks to understand how immigrants’ premigration political experiences influence the acquisition of party identification upon arrival in the United States. This research proposes that premigration political experiences influence the acquisition of party identification among Latino immigrants in the United States. Utilizing data from the 2016 Collaborative Multiracial Post-Election Survey (CMPS) and Proyecto Élites Parlamentarias Latinoamericanas (Latin American Parliamentary Elites Project), this paper analyzes how the ideology of the government in power in the immigrants’ country of origin influences party identification among Latino immigrants in the United States. Employing multinomial regression analysis, I demonstrate that the ideology of governments in power in Latin American countries when Latinos migrate influences the party identification of those immigrants in the United States. The results of this study contribute to the conversations on premigration experiences and challenge the applicability of classical theories of party identification for immigrants.
