This thesis investigates how gender and sexual minority identities shape political ambition and perceptions of welcomeness. Incorporating intersectionality theory, it examines willingness to run for office and perceived welcomeness in political spheres of identity groups compared to Cisgender Heterosexual Men who were selected as a control group. This is achieved using multiple regression models with progressive inclusion of socio-demographic and political variables. Data from a large survey highlight that some groups—such as Transgender Individuals—show higher political ambition; others, including Non-Binary Individuals and Cisgender Queer Women of Color, face compounded barriers. The results reveal that demographic and political engagement factors only partially mitigate these challenges. These findings underscore the need for targeted interventions to foster more inclusive, representative politics. In regards to intersectionality, this thesis proves that being part of multiple minority groups reduces perceived welcomeness but could not reach a solid conclusion in regards to race being a more prevalent factor than gender and sexuality.
