Support for gay marriage in Rhode Island is at an all-time high.

According to a Public Policy Polling survey of 614 Rhode Island voters released on Thursday, 57 percent of respondents support marriage equality, while 36 percent remain opposed. That's a 7 point increase in support and a five point decrease in opposition since the pollster last asked the question in 2011.

The survey comes a week after the Rhode Island House easily approved a marriage bill and sent it to the Senate.

“If public opinion has anything to do with it, Rhode Island will legalize gay marriage this year,” said Dean Debman, president of Public Policy Polling. “Voters in the state strongly favor it and support is increasing by the year.”

A large majority (85%) of respondents support either marriage (54%) or civil unions (31%) for gay couples. Only 13 percent say there should be no legal recognition of a gay couple's relationship.

Even among Republicans, who tend to be less supportive of gay rights, 75 percent at least support civil unions.
