A Gallup poll released today found that 53 percent of respondents believed "marriages between same-sex couples" should be legal, "with the same rights as traditional marriages." It's an all-time high--that question has never gotten more than 50 percent support in Gallup poll.
In one sense, this isn't quite news; Politico points out that other surveys have generated similar results in the past few months. In April, a CNN poll found 51 percent support for gay marriage, and in March, a Washington Post/ABC poll also found 53 percent support. Another CNN poll, last August, found 52 percent in favor of gay marriage.
Still, the Gallup poll is further evidence that support for gay marriage is climbing. Last year, Gallup found only 44 percent in favor of gay marriage, meaning there was a nine-point jump in support this year--the largest year-to-year change since Gallup began conducting annual polls about gay marriage in 2004. In April, Nate Silver at The New York Times noted that a similar jump was evident in the greater body of polling data.
Some other takeaways from the Gallup poll: In the past year, 13 percent more Democrats said that gay marriage should be legal, compared with 10 percent more independents. Meanwhile, Republicans had a zero percent change in opinion--according to Gallup, they don't support gay marriage any more now than they did a year ago.
Gallup finds that among people age 18 to 34, 70 percent support gay marriage; among people 55 and older, only 39 percent support it. "More broadly," the poll notes, "support is highest among younger women and lowest among older men." It's also higher "among those who attend church less frequently, among Catholics than among Protestants, and among those who are unmarried."
