The National Organization for Marriage (NOM) has pledged $250,000 to support New Hampshire lawmakers who vote for a bill that would repeal the state's 2-year-old gay marriage law.

Republican Representative David Bates last year introduced a bill that would replace the law with civil unions for any unmarried adults, including relatives, and would allow anyone to refuse to recognize such unions.

If approved, New Hampshire would become the first state to legislative overturn a gay marriage law.

“Sixty-one percent of New Hampshire GOP primary voters support a legislative definition of marriage as the union between a man and a woman alongside of a provision of civil unions,” NOM President Brian Brown said in a statement. “We intend to hold every legislator accountable for his or her vote on marriage. Those who support HB 437 will be rewarded, while those who don't will suffer the consequences in the next election.”

“We will consider a vote against the legislation a vote for same-sex marriage, and we will hold legislators accountable. NOM will support those who support marriage and will work with local New Hampshire organizations to recruit pro-traditional marriage candidates to run against those who vote against HB 437 and fund them,” Brown added.

Republican leaders last year decided to postpone debate on the bill until 2012. House Majority Leader D.J. Bettencourt last week said that a vote on the measure would not come up in the House until February.

A WMUR Granite State poll from the University of New Hampshire Survey Center found that only 27 percent of 500 randomly selected adults reached by telephone support repealing the law, while 50 percent are strongly opposed to repeal.

Approximately 2,000 gay and lesbian couples have married since the law took effect.

NOM has also vowed to derail gay marriage bills in Washington state and New Jersey.
