Support for same-sex marriage stays strong as party divide widens, poll shows
The Brief
A decade after the Supreme Court legalized same-sex marriage, 68% of Americans still support it, according to Gallup.
Support among Democrats has reached a record 88%, while Republican support has dropped to 41%, creating the largest-ever partisan gap on the issue.
Despite steady national support, the widening divide and political efforts to revisit past rulings may put same-sex marriage rights at risk.
WASHINGTON - It's been a decade since the Supreme Court made same-sex marriages legal across the U.S. in its ruling in Obergefell v. Hodges.
A recent Gallup poll said currently 68% of Americans still support the ruling.
By the numbers
According to Gallup, since 2021, about 68% to 71% of U.S. adults have supported same-sex marriage.
While overall support has stayed steady, party opinions have shifted.
Support among Democrats has hit a record high of 88%, and independents remain steady at 76%.

But Republican support has dropped from a high of 55% to 41%, the lowest since 2016.
The gap between Democrats and Republicans is now 47 points—the widest it's been since Gallup started tracking this issue 29 years ago.
Support for same-sex marriage was low in 1996, with only 27% of Americans in favor. By 2004, it rose to 42%, and in 2011, most Americans supported it for the first time. After the 2015 Supreme Court ruling, support jumped to 61% in 2016 and has stayed above that since.
Democrats have always been more supportive than Republicans, with independents generally closer to Democrats. A majority of Democrats have backed same-sex marriage since 2004, and independents since 2011. Support has grown among both groups. Republicans have only shown majority support twice—at 55% in 2021 and 2022—but that number has since dropped.
Why you should care
Gallup's May 1–18 poll showed that 64% of Americans say gay or lesbian relationships are morally acceptable. That number has stayed the same for the past three years. However, it is down from a high of 71% in 2022.
Most Americans have felt this way since 2010.
As with same-sex marriage, Democrats and Republicans are growing further apart. Right now, 86% of Democrats say same-sex relations are morally acceptable—a new high—while only 38% of Republicans agree, the lowest since 2012. Republican support peaked at 56% in 2022 but has dropped since then.
Independents are closer to Democrats on this issue, with 69% currently saying same-sex relationships are morally acceptable. Their views have stayed more stable over time.
Dig deeper
Even though national support remains high, the growing political divide could put LGBTQ+ rights at risk.
In 2022, Justice Clarence Thomas said the Supreme Court should reconsider past rulings, including those on same-sex marriage. Since then, some Republican lawmakers have pushed for the Supreme Court to overturn that decision.

President Donald Trump has also rolled back protections for LGBTQ+ people, especially transgender individuals. These actions suggest same-sex marriage could face new legal and political threats.
