In brief
In the newest Gallup survey, 65% of U.S. adults say same‑sex marriage should be legal—down from 71% in 2022—while only 37% of Republicans support it. Meanwhile, overall attitudes toward transgender people have also slipped, with only 40% of respondents finding gender‑affirmation morally acceptable. The findings underscore a widening partisan split on LGBTQ+ rights.
The newest Gallup poll shows that acceptance of same‑sex marriage and LGBTQ+ relationships in the United States has plateaued after more than two decades of steadily rising support, with declines most pronounced among Republicans.
A total of 65% of U.S. adults now say same‑sex marriage should be legal, down slightly from 71% measured in 2022 and 2023. The change largely reflects a quieter debate among Republicans; only 37% of Republicans say marriage between same‑sex partners should be both legally and morally acceptable. In the same cohort, 35% view gay and lesbian relationships as “morally acceptable” compared with higher numbers across other parties.

Data Show An Earlier Surge Then a Stagnation
Over the past 27 years, public opinion has seen a dramatic shift. In 1996 only 27% of adults endorsed legal same‑sex marriage. That number climbed steadily, peaking at around 70% a few years ago, before modestly declining in the most recent survey. Moral attitudes have mirrored this trajectory: in 2001 only a quarter of Americans deemed same‑sex relations morally acceptable, while today's figure sits at 62%.
These numbers represent the direction of policy at the federal level—after the 2015 Supreme Court ruling on Obergefell v. Hodges—as well as the continuing same‑sex marriage bans that still appear in state bills and court challenges.
The graphic above, created by AP Interactive, illustrates sharp divergences in party‑level support. While Democrats and independents maintain stable levels of approval, Republicans display a noticeable dip in both legal and moral acceptance.
The Turbulent Landscape of LGBTQ+ Legislation
Legal battles continue to shape public policy on LGBTQ+ rights. Although same‑sex marriage remains legal nationwide, court challenges persist, raising fresh questions about the scope of federal protection. In recent months, the highest court again considered, with no comment, the possibility of reversing the 2015 ruling, citing Justice Clarence Thomas’s concerns about the precedent.
State‑level initiatives reflect a mixed response. The Southern Baptist Convention loudly called for a nationwide repeal of the Supreme Court victory last year. Likewise, across the country state legislators have introduced bills ranging from attempts to ban same‑sex marriage to efforts to protect it. The Tennessee House endorsed a bill that allows private entities to refuse recognition of same‑sex unions, while Idaho passed a resolution seeking judicial review of the 2015 decision.
In parallel, the Trump administration in recent months has pushed a suite of executive orders seeking to restrict transgender rights on a federal level, including a now‑overturned ban on transgender military personnel. In the past five years Republican‑controlled states have also enacted laws that prohibit gender‑affirming medical treatment for minors, limit bathroom access for transgender people, and exclude transgender girls or women from certain sports competitions.
In a way mirroring attitudes toward same‑sex marriage, public comfort with trans‑gender identity has slipped slightly. The new poll reports that 40% of respondents find changing one's gender morally acceptable—a decline from nearly 50% last year. Of those, only 45% of Republicans express moral acceptance, a dip that traces back to more aggressive campaign rhetoric and the recent headlines on state and federal policy changes.
Polling Methodology
This May study was conducted by telephone with a nationally representative random sample of 1,001 U.S. adults. The margin of error for national responses is ±4.0 percentage points. Detailed methodological notes are available in the survey's appendix on the Gallup website.
Gallup notes that the survey used a balanced weighting methodology to align with the U.S. Census percentages for age, sex, race, ethnicity, region and education. Respondents were asked to provide unambiguous answers to questions about legal and moral acceptance of same‑sex marriage and transgender issues.

The data reveal a clear partisan fissure that underscores how clearly evolving social norms have become linked to political identification in the United States.
