Gallup: Partisan support of same-sex ‘marriage’ hits record divide

The split between Republicans and Democrats in support of valid same-sex “marriage” widened to a 47-point gap — a new record — in 2025, according to a May Gallup analysis.

Ten years after Obergefell v. Hodges, the 2015 landmark Supreme Court case that gave same-sex couples the right to get married, Gallup discovered that 68% of Americans say that same-sex marriage should be recognized as valid and given the same rights as marriage between a man and a woman.

Broken down by political party, Gallup found that 41% of Republicans currently think that same-sex marriage should be valid, compared with 88% of Democrats who say the same thing, a record high for the party. Republicans’ support for same-sex marriage peaked in 2021 and 2022, registering at 55%.

Gallup also found that 64% of Americans say that same-sex relations are morally acceptable, down slightly from the 71% recorded in 2022 but consistent with recordings in 2023 and 2024.

As with support for valid same-sex marriage, the divide between Republicans and Democrats’ approval of same-sex relations has continued to grow. A record 86% of Democrats now view same-sex relations as morally acceptable, while just 38% of Republicans agree — the party’s lowest level since 2012.  

Republicans’ views on the morality of same-sex relations declined drastically between 2022 and 2023, going from 56% to 41% and steadily declining in the following years.

According to Gallup, most US demographics say that same-sex marriage should be valid and consider same-sex relations to be morally acceptable, but adults who attend church weekly are the least likely to support either issue. Only 33% of weekly churchgoers think same-sex marriage should be valid and only 24% say same-sex relations are morally acceptable.
