Partisan divide on same-sex marriage largest in almost 30 years: Gallup

Republicans and Democrats are more divided in their support for same-sex marriage than they’ve been at any point since Gallup began polling the issue nearly 30 years ago.

The May 2025 poll shows a 47-point gap between parties: 88 percent of Democrats and 41 percent of Republicans said marriages between same-sex couples should be recognized by law as valid, with the same rights as traditional marriage.

Last year, Republicans and Democrats were separated by 37 points; in 2023, they were separated by 35 points; in 2022, by 32 points; and in 2021, by 28 points. In 2020, 34 points separated the two groups.
