Gallup’s May 2-7 poll suggests Americans’ support for gay marriage is solidifying above the majority level. Recently, Rhode Island and Delaware legalized same-sex marriage, and Minnesota is likely to follow suit. That would bring the total number of states legally recognizing same-sex marriage to 12.
Just three years ago, support for gay marriage was 44%. The current 53% level of support is essentially double the 27% in Gallup’s initial measurement on gay marriage, in 1996.
Nearly all U.S. subgroups are more likely to favor gay marriage now than in the past. Politically, Democrats, independents, and liberals all show increasing support for gay marriage over time, with each well above the majority level now. Republicans, conservatives, and moderates are more likely to favor gay marriage now than in 1996, but the increase in support among these groups may have stalled. Thus, most of the increase in the percentage favoring legal gay marriage in the last three years has come among left-leaning groups politically.
