Public support for LGBTQ+ rights and same-sex marriage has declined measurably in the United States, according to new data from Gallup released on Tuesday. The findings mark a notable reversal of a decades-long trend toward increasing acceptance, with support for issues including same-sex marriage and the moral acceptability of gay and lesbian relations falling from recent peaks.

The Gallup survey shows the drop is not confined to one political group. Republican support for marriage equality has also softened, suggesting the shift reflects broader cultural dynamics rather than solely partisan realignment. The decline follows years of legal and legislative battles over LGBTQ+ issues at the state and federal level, including debates over gender-affirming care, bathroom access policies, and parental rights in schools.

Polling experts caution that single-year fluctuations can reflect short-term political climate effects rather than permanent attitude changes. Still, the magnitude and consistency of the decline across multiple questions in the Gallup survey have drawn attention from researchers who track social attitudes over time. Gallup has conducted similar surveys for decades, giving the data a long baseline for comparison.

The release of the poll coincides with the beginning of Pride Month, amplifying its visibility. Advocacy groups on both sides of the debate have cited the findings to support their respective positions on pending legislation and court cases affecting LGBTQ+ Americans. Policymakers and political strategists are also expected to weigh the data as the 2026 midterm election cycle intensifies.
