The impact of party competition on LGBTI+ rights: Evidence from Spanish autonomous regions (1990–2022)

Abstract

AbstractPolitical competition accelerates the enactment of lesbian, gay, bisexual, trans*, and intersexual rights (LGBTI+) due to the dynamic, rational behavior of mainstream parties across the political aisle to adapt to the sociopolitical environment. We argue that LGBTI+ social movements capitalize on median voter shifts combined with the rising pressure of ideologically close challenger parties to enact legislation. To examine this argument, we employ quantitative event history analysis with a unique dataset with measures for social movement, institutional, political, and sociocultural dimensions across 33 years in Spanish subnational arenas. We find that rising leftist and liberal contenders challenging dominant center‐left and center‐right parties, respectively, widen the opportunity political structure of LGBTI+ organizations. Ultimately, rising political fragmentation in a multiparty, multidimensional party system turns both left and right mainstream parties into allies of LGBTI+ organizations, which propose new legislation, due to political platforms seeking to preserve and enhance their electoral base.Related ArticlesBurnett, Craig M., and Aaron S.
