Gallup: Sixty percent of Americans now support same-sex marriage, as the Supreme Court prepares to rule on its constitutionality next month. This is up from 55% last year and is the highest Gallup has found on the question since it was first asked in 1996.
“While there has been uneven growth in support among Republicans versus Democrats, both groups have become more supportive. The remaining broad partisan divide, however, underscores how contentious the issue will continue to be as the 2016 election process unfolds.”
Another Gallup poll finds that “for the first time, a majority of Americans say same-sex orientation is something gays and lesbians are born with rather than something that is determined by their upbringing or environment.”
Washington Post: Glen Bolger of Public Opinion Strategies provides a reason for these changes in public opinion: “I think the shift is because as more and more gays came out of the closet, people realized they know gays personally, and that makes a huge difference in attitudes … Once Americans became comfortable with gays on a personal level, it became easier to reconcile their opinions toward gays, and shift on gay marriage.”
