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

A new Gallup survey finds that American support for same-sex marriage has declined modestly for the first time in more than twenty years, falling to 65 percent from 71 percent in both 2022 and 2023. The shift is concentrated almost entirely among Republicans, whose backing dropped to 37 percent. Democrats and independents held steady at high levels of support, underscoring how the issue has become another marker of deepening partisan division rather than a source of broad national consensus.

The May poll also recorded a parallel softening on the moral acceptability of gay and lesbian relations. Only 35 percent of Republicans now view those relationships as morally acceptable. National figures on that question remain higher, but the Republican decline has pulled the overall average down after years of steady gains. Gallup has tracked these attitudes since the mid-1990s, when just 27 percent of adults favored legal recognition of same-sex marriage. Support rose gradually through the 2000s and accelerated after the 2015 Supreme Court decision in Obergefell v. Hodges. The recent reversal ends a long period of upward movement that once appeared durable across party lines.

Gallup analyst Jeffrey Jones noted that Republican attitudes had tracked the national trend upward until recently. He pointed to the 2024 presidential campaign as one possible influence, when Republican candidates emphasized cultural issues including restrictions on transgender participation in sports and access to medical care. Since taking office, the Trump administration has moved to scale back federal diversity initiatives and has issued directives limiting transgender individuals’ access to certain federal programs and documents. These steps have occurred alongside continued Republican appointments of openly gay officials, illustrating the party’s uneven approach to LGBTQ issues.

The data arrive against a backdrop of state-level activity on related questions. Several Republican-led states have enacted limits on gender-affirming care for minors and on classroom discussion of sexual orientation. Democratic-led states have moved in the opposite direction, expanding legal protections and funding. The Gallup findings suggest these state differences now align closely with national opinion splits rather than cutting across them.

Independent support has remained largely unchanged, hovering near two-thirds. That stability indicates the national decline is not the product of a broad public rethinking but of one party moving away from positions it had gradually adopted. The pattern mirrors trends on other cultural questions where Republican voters have consolidated around more traditional views while Democratic voters have moved further in the opposite direction.

Advocates on both sides interpret the numbers differently. Groups favoring expanded LGBTQ rights see the Republican retreat as evidence that political leadership can reverse earlier gains. Conservative organizations argue the poll reflects a healthy correction after rapid social change. Neither reading alters the core finding that overall public acceptance has stopped rising and that the partisan distance on the issue has grown measurably in the last three years.
