The U.S. government continues to deport large numbers of undocumented Latino immigrants. In this new article, authors Alex Street, Chris Zepeda-Millan, and Michael Jones-Correa address the likely effects of these policies on Latino partisanship. Usiung a survey experiment to test the effects of information about mass deportations on partisan evaluations among young second-generation Latinos, the authors find that young U.S.-born Latinos view the Democratic Party as less welcoming when informed that deportations have been higher under President Obama than under his predecessor. Because most young U.S.-born Latinos are either weak partisans or political independents, there is wide scope for information effects among these potential voters. The authors find that mass deportation policies have the potential to reshape the partisanship and politics of Latinos for years to come.
