The Group-Basis of Political Behaviour among Minoritized Communities: The Case of LGBTQ+ Linked Fate and Sexual and Gender Minorities

LGBTQ+ individuals often display consistent political behaviour despite being internally diverse. We theorize about the importance of group-based heuristics to understand this cohesiveness by proposing the concept of LGBTQ+ linked fate. First, we argue that LGBTQ+ linked fate is stronger among privileged individuals within the LGBTQ+ community (white, cisgender, gays/lesbians) and among those whose life experiences have made their LGBTQ+ identity salient. Then, expanding on social identity theory, we posit that individuals with greater LGBTQ+ linked fate are more likely to hold group-based political attitudes and voice these preferences through electoral participation. We provide support for these claims using a novel oversample of ∼2,000 LGBTQ+ Americans from the 2020 Collaborative Multiracial Post-Election Survey. We show that stronger LGBTQ+ linked fate is associated with higher voter turnout, leaning ideologically liberal, and identifying with the Democratic Party. This study contributes to understanding group identity, solidarity, and political behaviour among marginalized communities.
