On January 1, New Hampshire became the latest state to legalize gay marriage. Fifty-four gay couples married on the day the law took effect. But opponents are mounting a campaign to undo those marriages, the Washington Post reported.

Representative Alfred Baldasaro, a Republican from Londonberry, is the primary sponsor behind a bill that would repeal the law. Baldasaro testified Tuesday at a House Judiciary Committee hearing on the measure.

“A man and a woman together create a family where individuals of the same gender cannot create a family,” Rep. Jordan Ulery, a Republican from Hudson, testified.

But Representative Ed Butler, an openly gay Democrat, urged the committee to reject the proposal.

“Marriage is an incredible acknowledgement of our equality. Please don't take it away after so shortly having given us the opportunity to feel the incredibly powerful stamp of access to that word. Marriage is a powerful word.”

House members are also considering a bill that would put a gay marriage ban in the state constitution.

Opponents concede the Democrat-controlled Legislature is unlikely to reconsider its decision this year, but they hope to use the issue to alter the political landscape in their favor in November.

State Representative David Bates, a Republican from Windham, is behind a grassroots effort to raise the issue at town hall meetings this spring. The campaign encourages people to put a non-binding resolution calling for a vote on gay marriage before town voters. Bates said he expects a large majority of New Hampshire's towns will put the issue on the agenda.
