Previous research from the United States suggests that having voted for a losing-side candidate in presidential elections is associated with individual feelings of exclusion and social pain, reactions usually observed in interpersonal or small-group instances of exclusion. The current research replicates these findings for voters of losing-side parties in a field study on a real election in a European country (Austria; Study 1), demonstrating that findings hold within a different political system. Moreover, we add experimental support for the causal effect of electoral loss on feelings of exclusion and social pain reactions in a two-party (Study 2) and a multiparty context (Study 3). We further extend previous research by demonstrating that postelectoral need-threat likely translates into behavioral intentions on a societal level (Studies 1–3). The current findings add to an emerging line of research on the importance of individual feelings of exclusion in politics by integrating small-group research with macropolitical behavior.
