A majority of Maryland voters say they would keep a recently approved gay marriage law if it were put up for a vote, The Baltimore Sun reported.

The poll, commissioned by Marylanders for Marriage Equality and conducted by Public Policy Polling, shows a narrow majority (52%) of respondents say they would “probably” or “definitely” keep the law, while 44 percent said they would “probably” or “definitely” vote against a referendum on the issue.

“Momentum is on the side of making Maryland families stronger,” Kevin Nix, a spokesman for Marylanders for Marriage Equality, told the paper.

Governor Martin O'Malley earlier this month signed a gay marriage bill approved by lawmakers into law, making Maryland the eighth state to legalize gay marriage.

Opponent have vowed to put the law up for a vote in November. Nearly 56,000 valid signatures, one-third of which would need to be submitted by May 31, with the remainder by June 30, are needed to put the measure on the ballot. The campaign is being organized by Maryland Marriage Alliance, which is supported by the National Organization for Marriage (NOM).

Other recent polls by Gonzales and The Washington Post have put the question much closer to 50-50.
