​Poll: Americans' views on same-sex marriage

By Sarah Dutton, Jennifer De Pinto, Anthony Salvanto, and Fred Backus

As the Supreme Court considers its ruling on same-sex marriage, 54 percent of Americans think there should be a federal law regarding same-sex marriage for all fifty states.

Fifty-seven percent of Americans support legalizing same-sex marriage. Majorities of Democrats (69 percent) and independents (59 percent) support it, while 55 percent of Republicans do not.

Thirty percent of those who now support legalizing same-sex marriage say they once held the opposite view.

Although the decision as to whether to legalize same-sex marriage is currently made at the state level, the Supreme Court now has the opportunity to interpret federal law to make same-sex marriage legal in all fifty states. A majority of Americans seem ready for one law of the land: 54 percent think there should be one federal law for all states regarding same-sex marriage, while 41 percent think it should be left to each individual state to decide.

Supreme Court could set national same-sex marriage standard

Most Americans who support legalized same-sex marriage think it should be decided by one federal law (66 percent), while most Americans who oppose it think it should be left up to the states to decide (54 percent).

As they have for more than two years, a majority of Americans (57 percent) say it should be legal for same-sex couples to marry. Public opinion has changed quickly on this measure - as recently as July 2012, Americans were divided on the issue, with only 46 percent saying same-sex marriage should be legal and 44 percent saying it shouldn't be legal.

The poll further suggests the extent to which people's views have changed. Thirty percent of Americans who now think same-sex couples should be allowed to legally marry say they once held the opposite view. When asked why they changed their minds, one in five volunteered that they are more educated about the topic now (21 percent). Other reasons included knowing someone who is gay or lesbian (12 percent), that it's none of their business (9 percent), that it's the modern way of thinking (6 percent), that same-sex couples should have equal rights (5 percent), and that it's already legal in some states (5 percent).

Americans of all ages are now more likely to say same-sex marriage should be legal than say it should not, including most Americans under the age of 55, as are Americans of all income and education levels. Politically, majorities of Democrats (69 percent) and independents (59 percent) think same-sex marriage should be legal, while over half of Republicans (55 percent) think it should not be.

Supreme Court to decide big cases over next two weeks

Most Americans don't think being gay or lesbian is a choice. Today just under a third of Americans now think being gay or lesbian is something people choose to be, while 54 percent think it is something people cannot change. Twenty-two years ago, Americans were divided when they were asked whether being homosexual was a choice, with 44 percent who said being gay is a choice, versus 43 percent who said it was something that couldn't be changed.

Americans who say being gay or lesbian is something a person cannot change are far more likely to say same-sex marriage should be legal (78 percent), compared to those who say it is a choice (30 percent).
