Majority of Republicans support same-sex marriage for the first time, poll finds

For the first time since Gallup started tracking Americans views on gay marriage, a majority of Republicans say they support it.

Support for same-sex marriage has reached 70% for the first time, according to a Gallup poll released Tuesday. When Gallup started asking Americans about their opinions on same-sex marriage in 1996, 27% approved of it but support rose gradually and reached a majority level in 2011 for the first time.

The survey, conducted May 3-18, is based on a sample size of 1,016 adults with a margin of error of plus or minus four percentage points.

A small majority — 55% — of Republicans said they support gay marriage in the latest poll, compared to 16% who approved when asked about same-sex marriage in 1996.

After the landmark Supreme Court “Obergefell v. Hodges” decision in 2015, which legalized same-sex marriage in all 50 U.S. states and Washington D.C., overall support grew from 60% in 2015 to 67% in 2018.

“Once opponents of legalization, Republicans have mostly come to back it. Court and legislative challenges to the legal status of same-sex marriage have simmered down since the Supreme Court issued its decision,” Gallup researchers wrote.

Democrats have the strongest support of same-sex marriage, with 83% saying they approve in both 2018 and this year. More independents also support gay marriage, with 73% saying they approve compared to 68% to 71% who said the same from 2017 to 2020.

“On LGBT rights, everyone has moved on this issue,” Robert Jones, the founder of Public Religion Research Institute poll, told the the New York Times. “Whether you’re talking about marriage equality, nondiscrimination protection — everybody has moved. Seniors have moved, white evangelicals have moved, base Republicans have moved.”

According to a 2019 Pew Research Center poll, 44% of Republicans surveyed said they support same-sex marriage.

Among religious respondents, 66% of “white mainline Protestants” and 61% of Catholics said they support gay marriage, according to Pew.

Although white evangelical Protestants have the lowest support among religious groups, approval has grown from 13% in 2001 to 29% in 2019, according to Pew.

“The increase in the share of adults who favor same-sex marriage over the past 15 years is due in part to generational change. Younger generations express higher levels of support for same-sex marriage,” the Pew survey reads.

Gallup also found that support for same-sex unions differed by age group. In the latest survey, 84% of those ages 18-34 said they support same-sex marriage while 72% of respondents ages 34-54 and 60% of those 55 and older said the same.
