US Support for Same-Sex Marriage Plateaus, Decline Seen Among Republicans

Support for same-sex marriage and relationships in the U.S. has plateaued after more than two decades of consistent growth, with a notable decline now observed among Republicans, according to a new Gallup poll. The findings indicate a subtle but significant shift in public opinion, particularly along partisan lines. Currently, 65% of U.S. adults believe same-sex marriage should be legal, a slight decrease from 71% recorded in both 2022 and 2023. This downturn is primarily driven by a drop in acceptance among Republican voters. The May survey revealed that only 37% of Republicans consider same-sex marriage legally valid, while 35% deem gay and lesbian relations "morally acceptable." In contrast, the views of Democrats and independents remain largely stable, with majorities in both groups affirming the legality of same-sex marriage and the morality of gay or lesbian relationships. This widening partisan divide is also reflected in broader policy debates surrounding LGBTQ+ issues across the country. The recent dip in support, though modest, is striking given the dramatic evolution of American attitudes on the issue. In 1996, Gallup data showed only 27% of U.S. adults supported legal same-sex marriage. This figure steadily climbed, peaking a few years ago with approximately seven in 10 adults backing its legality. Similarly, opinions on the morality of same-sex relationships saw a significant increase, rising nearly 30 percentage points from 40% in 2001. However, recent data suggest a reversal, with the new poll finding 62% of U.S. adults view gay and lesbian relations as morally acceptable, down from 71% in 2022. Despite these shifts in public opinion, same-sex marriage has been recognized nationwide since a landmark 2015 Supreme Court ruling. This decision followed a 12-year period during which court rulings and state laws progressively legalized it across most states. By last year, over 800,000 married same-sex couples were recorded, according to data compiled by the Williams Institute at the University of California, Los Angeles, School of Law. Nevertheless, efforts to challenge the ruling persist. Last year, a call to overturn the 2015 decision reached the Supreme Court, echoing Justice Clarence Thomas's earlier statements advocating its reversal, but the court declined to hear the appeal without comment. The Southern Baptist Convention also overwhelmingly voted last year to reverse the ruling and impose a ban. Furthermore, lawmakers in at least 11 states introduced legislation during recent sessions aimed at banning same-sex marriage, with measures in the Tennessee and Idaho Houses gaining some traction. Conversely, a similar number of states have introduced measures designed to protect same-sex marriage.
