From the late 20th and into the early 21st centuries, scholars in the field of lesbian, gay, bisexual, transgender, and queer (LGBTQ) politics have produced a substantial body of literature that explores and explains the political attitudes and behavior of sexual and gender minorities. The interdisciplinary nature of the field is reflected in the broad range of approaches and theories that attempt to explain political phenomena among LGBTQ people. The majority of the literature reveals sexual minorities to be politically distinct from heterosexuals, in that sexual minorities are more ideologically liberal and, in the United States, more likely to support Democratic partisans. Largely because of heterosexism, sexual and gender minorities are also more likely to participate in political activities that directly implicate their sexual orientation or gender identity, such as volunteering with LGBTQ interest groups or attending “Pride” events, although sexual orientation and gender identity are significant predictors of a variety of attitudes and behavior. Recent research has demonstrated that LGBTQ people also participate in politics by running for office, mounting legal challenges to discriminatory laws or government actions, and collectively organizing locally, nationally, and internationally. Explanations for LGBTQ political distinctiveness have concentrated in three broad areas: selection, embeddedness, and conversion theories. While studies have provided supportive evidence for each hypothesis, the field has also increasingly turned to intersectional evaluations that admonish researchers to interrogate intragroup LGBTQ behavioral and attitudinal heterogeneity more fully. The infusion of intersectional theory into LGBTQ political research has revealed attitudinal and behavioral distinctions among sexual and gender minorities centered on axes of race and ethnicity, nationality, religion, age, and income, among others. The critical importance of disentangling the concepts of sexual orientation and gender identity, the recognition of cross-cutting structures of oppression such as homophobia, sexism, and racism, and the emergence of subfields of LGBTQ political behavior are indicative of a burgeoning field of study. Looking to the future of LGBTQ political research, the political successes of the LGBTQ movement and evolving conceptions of sexual and gender identity have necessitated a reevaluation of LGBTQ political behavior in the 21st century. The continued diffusion of same-sex marriage, the electoral capture of LGBTQ voters, and the destabilization of identity categories that has been demanded by queer theory all pose unique challenges to the future of LGBTQ politics and political mobilization around the globe.
