A decade after the Supreme Court’s landmark Obergefell v. Hodges decision legalized same-sex marriage across the United States, public support for marriage equality appears to be slipping—particularly among Republicans. In 2004, when Massachusetts became the first state to legalize same-sex marriage, it faced broad political and public opposition. But by 2015, support had grown significantly, turning what was once a controversial issue into settled national law. However, recent surveys, such as the General Social Survey, show a reversal of that trend: while Democratic support has risen slightly, from 77% in 2018 to 80%, Republican support has dropped from 58% to just 45%.
This decline is not merely symbolic—it is influencing political and legal efforts. Republican lawmakers in states like Michigan, Idaho, and Montana have introduced proposals aimed at challenging Obergefell, and the Southern Baptist Convention has called for its reversal. Though the Supreme Court is unlikely to overturn the ruling—only Justice Clarence Thomas has openly suggested doing so—experts warn that other decisions, like those allowing businesses to refuse service to LGBT couples on religious grounds, are chipping away at the broader support and protections surrounding same-sex marriage.
The reasons behind this shift are complex. Changing demographics within the Republican Party, including gains among socially conservative minorities and less educated voters, have likely contributed. Additionally, the politicization of transgender issues—especially in youth healthcare and sports—has influenced attitudes toward gay rights more broadly. Many Americans now conflate the two causes, with opposition to trans rights often overlapping with opposition to same-sex marriage. Political scientists note that rapidly formed public opinions, such as the swift rise in support for gay marriage, can be fragile and subject to reversal.
While the right to marry may remain legally protected for now, experts think that the battle for full equality is far from over. Subtle legal challenges—such as limiting adoption rights or refusing to recognize both parents in same-sex unions—could erode hard-won gains. What once seemed like settled ground for LGBTQ+ rights is again becoming politically unstable, leaving many advocates concerned about the future.
