A majority of Americans would support a Supreme Court ruling striking down state bans on gay marriage.

The high court in April heard oral arguments in a case challenging bans in Ohio, Tennessee, Michigan and Kentucky. The case stems from the nation's first – and so far only – federal appellate court ruling upholding such bans as constitutional. A ruling, expected sometime this month, could strike down the nation's remaining 13 bans, leading to nationwide marriage equality.

According to a Quinnipiac University telephone survey of 1,711 registered voters conduced from May 19 to 26, 56 percent of respondents said that they would support the Supreme Court finding that “same-sex couples have a constitutional right to marry,” while 38 percent said that they would oppose such a ruling.

While a majority of Republicans (62%) were opposed to a potential decision, majorities of Democrats (70%) and independents (61%) favored it.

Respondents also oppose state marriage bans by a 53-40% margin.

When asked, “Do you support or oppose requiring states to recognize same-sex marriages performed legally in other states?” a majority (57%) of people polled answered that they support such action.
