Gallup Poll Finds Republican Same-Sex Marriage Support at 37%

A new Gallup poll shows that American support for legal same-sex marriage has fallen modestly for the first time in years. Overall backing stands at 65 percent of adults, down from 71 percent in both 2022 and 2023. The shift traces almost entirely to Republican respondents, whose approval dropped to 37 percent.

Gallup has tracked the question since the mid-1990s. In 1996 only 27 percent of adults favored legal recognition. Approval rose steadily for more than two decades, reaching roughly seven in ten adults by the early 2020s. The same pattern held for views on the morality of same-sex relations, which climbed from 40 percent in 2001 to near 70 percent before leveling off.

Republican support had followed the national trend upward until recently. It reached 55 percent in 2021 and 2022 before falling back to levels last seen around 2015. Democratic and independent responses remained largely unchanged, with majorities in both groups continuing to endorse legality and moral acceptability.

The survey, conducted in May, also asked about the morality of gay and lesbian relationships. Thirty-five percent of Republicans called such relations morally acceptable, a figure that aligns with the decline in marriage support. Broader questions on LGBTQ policies show similar partisan gaps, though those items were not the focus of the current release.

Gallup analyst Jeffrey Jones noted that earlier gains occurred across party lines but that movement has reversed among Republicans. He pointed to the 2024 campaign period as one possible influence on attitudes. Federal policy changes since then, including limits on certain diversity programs and restrictions tied to transgender issues, have kept the topic in public debate.

Long-term data indicate that public opinion on marriage evolved over more than twenty years before the recent plateau. The current dip remains small in national terms yet marks the first sustained reversal in the Republican subgroup after years of convergence. Future surveys will show whether the pattern holds or returns to prior trends.
