Support for the legalization of same-sex marriage in the U.S. matched an all-time high, according to a Gallup report published June 1.
When asked, “Do you think marriages between same-sex couples should or should not be recognized by the law as valid, with the same rights as traditional marriages?” 67% of respondents said it “should be valid.”
This matches 2018 for an all-time high in polling history and is a 40-point increase from 1996.
Matching the all-time low from two years ago, 31% of respondents said same-sex marriages “should not be valid” – a 37-point decrease in those who held this position 24 years ago.
In 2011, more respondents said same-sex marriage should be recognized by the law as valid (53%) than those who said it should not be valid (45%) for the first time in polling history.
While Democratic respondents continue to be the most likely group to affirm same-sex marriage (83% did so in 2020), support has been increasing among both independents (71%) and Republicans (49%) as well.
This is an all-time high for Republican respondents and it matches the all-time high from 2018 for both Democrats and independents.
Since 1996, Democrats have seen a 50-point increase in support, compared to a 39-point increase among independents and a 33-point increase among Republicans.
The margin of error is plus-or-minus 4%.
