A plurality of Washington state voters would vote to keep the state's recently approved gay marriage law.

Governor Chris Gregoire earlier this month signed into law a gay marriage bill approved by lawmakers. Gay and lesbian couples may wed in the state starting on June 7.

That is, provided opponents do not gather sufficient signatures to put the law up for a vote. In which case marriage equality would be put on hold pending the outcome of a November election.

Referendum 74 supporters insist the public will vote to end gay marriage in the state. But in 2009, voters rejected an effort to repeal a domestic partnership law dubbed “everything but marriage” which gave gay couples all the protections of married heterosexual couples.

According to a Public Policy Polling survey of 1,264 Washington voters released Wednesday, supporters of the marriage law outnumber opponents.

Fifty percent of voters say they'll vote to uphold the law, while 46 percent say they would vote to repeal it.

A large majority of voters (78%) also support either marriage (46%) or civil unions (32%) for gay couples. Only 20 percent of respondents said there should be no legal recognition of a gay couple's relationship.

“Even 59% of Republicans at least support civil unions,” the survey's authors noted in announcing their results. “That may bode well if there's a repeal vote this fall – almost all voters in the state are at least somewhat accepting of same-sex relationships.”
