How Are Social Groups Linked to the Vote? Social Group Perceptions and Party Choice

Abstract Interest in the influence of subjective perceptions of social groups on political behaviour is increasing. While most extant work has focused on voters’ social identities and their related, expressive considerations about the social bases of parties, this article directs attention to two other considerations that may also influence the vote: voters’ evaluations of social groups, as suggested by reference group theory, and their instrumental considerations about the extent to which parties work to advance the interests of specific groups. Using both an observational ( N = 2,065) and a preregistered experimental study ( N = 7,090) about voter evaluations of social classes and the extent to which parties are seen as fighting for them in Denmark, the study shows how these considerations influence party choice over and above the influence of identity-based considerations. Thereby, the study is the first to show experimental evidence for the effect of group evaluations on vote choice.
