A new Gallup poll suggests that support for same-sex marriage and related relationships in the United States is no longer increasing after decades of growth. Across multiple reports, the outlets say the level of support has flattened and shows a modest decline among some groups. Gallup finds that about 65% of U.S. adults believe same-sex marriage should be legal, which is slightly lower than recent figures cited for 2022 and 2023, when support was reported at about 71%. The coverage also notes that while acceptance has grown over the last two decades overall, the recent pattern includes an ongoing downtick among Republicans. The reports describe the change as a pause in the long upward trend rather than a sudden reversal, emphasizing that the overall public support remains well above earlier levels from years past. The outlets present the poll as evidence of shifting public opinion dynamics, with different political groups showing different trajectories.
