The Substantive Effects of Descriptive Representation: Gay and Lesbian Members of Congress Are More Supportive of Gay Rights

ABSTRACT The descriptive representation of stigmatized groups has numerous benefits both to group members and society at large. We study the extent to which LGB members of the US Congress provide increased support for LGBT rights. While LGBT substantive representation has been studied extensively, descriptive representation has been examined extensively at only the local and state levels. The absence of research at the federal level is important because federal policy is essential to expanding gay rights. We overcome issues related to the small number of openly LGBT Members of Congress and the few bills either introduced or receiving votes by examining LGB legislators over 24 years (i.e., 6,425 legislator–Congress pairs) using Human Rights Campaign scores. Using Coarsened Exact Matching, we find a substantively small but statistically significant and consistently positive effect: LGB members of Congress are more supportive of LGBT rights than other members with a similar background and from a similar district. The use of matching may provide a useful approach for scholars who are interested in studying the link between descriptive and substantive representation for other small groups.
