New Hampshire State Rep. Seth Cohn has warned against repeal of New Hampshire's gay marriage law, The New York Times reported.

In 2009, Democrats legalized gay marriage in the state. The following year, Republicans gained control of the House and Senate, and the law came under constant threat of repeal.

However, not all Republicans are on board with making New Hampshire the first state to legislatively overturn a gay marriage law.

Rep. David Bates' plan to replace the law with civil unions for any unmarried adults, including relatives, stumbled out of the gate. The House shelved the bill last year after holding a heated hearing on the issue. And Republican leaders who promised to revisit the bill in January have yet to do so.

Bates, a Republican, told the Times that he was willing to tinker with the bill's language in order to win over fence-sitters.

He said he was willing to change or remove a sentence that states, “Children can only be conceived naturally through copulation by heterosexual couples.”

“I recognize there's things in it that some aren't happy with,” he told the paper, “so we're going to change it, get it to a place where as many people as possible are comfortable with it.”

Bates' bill would also allow anyone to refuse to recognize a civil union.

An October survey found few New Hampshire voters (27%) in favor of repeal. And while Republicans dominate the Legislature – making passage a near certainty – opposition from libertarian-leaning Republicans has cast doubt on whether there is sufficient support to override a promised veto from Democratic Governor John Lynch.

Cohn urged colleagues to drop the effort.

“They want this as an election issue,” he said of the Democrats. “I think it's going to backlash against the Republicans who, in the face of the polls, are choosing not to believe the average person is OK with this situation.”
