These data are from a July 8-12 Gallup poll, conducted about two weeks after the Supreme Court’s 5-4 decision in Obergefell v. Hodges legalized gay marriage nationwide. The court’s ruling on the practice, which was legal in the majority of states, so far has not affected the way Americans feel about the issue.
However, the decision was consistent with American public’s opinion on the issue. Americans’ support for gay marriage has increased over time, from 27% in 1996, the first time Gallup asked about it, to the current 58%. A consistent majority has favored it since 2011, including a high of 60% in May of this year. The two-percentage-point difference between the May and July estimates is not statistically meaningful.
Politically, Democrats (74%) are most likely to support same-sex marriage, followed by independents (62%). Republicans (30%) remain least likely to support it, with a majority (67%) still opposed.
