Five experiments show that Republicans and Democrats respond to this demographic change with divergent reactions in three domains: perception of threats, celebratory reactions, and emotional responses. In terms of threat perceptions, Republicans tend to perceive Muslim population growth as a threat to Christians and U.S. society in in terms of American culture, legal norms, and peace. Furthermore, Republicans are less likely to have celebratory reactions to Muslim population growth (a theoretically novel reaction). They experience less hope and pride, along with more anxiety and anger. The divergent responses from partisans are partially explained by citizens’ ideological orientation and media exposure, but they are not explained by any racial mechanisms or the partisans’ religious identity. Together, these studies reveal that political leaning can be an antecedent to reactions to the demographic change in many complex ways beyond the dominant group’s concern for their status.
