A Christian conservative New Hampshire group on Monday said it would make another attempt to repeal gay marriage in the upcoming legislative session.

Cornerstone Policy Research's legislative agenda is based on its Families First Pledge for candidates.

Under the pledge's section concerning marriage, the group states it will work to “pass a law that repeals gay 'marriage' and either restores civil unions for homosexuals or restores the pre-civil union law in New Hampshire.”

“We fully expect our pledge signers to introduce bills identified in our agenda,” spokesman Shannon McGinley said in a statement.

She said more than 85 candidates had signed the pledge. Monday was the first day incumbent House members could file bills.

Possibly on board is New Hampshire House Speaker Bill O'Brien, who said in July that he would make another attempt to repeal the law if re-elected speaker.

“If our families are weak, then we’ll never be able to have final fiscal responsibility, because if government needs to step up for weakened families then there’s going to be an unlimited call on government resources. One of the things that makes our families strong is a traditional definition of marriage and I firmly believe that,” O'Brien said during an appearance on New Hampshire Public Radio's the Exchange.

Last March, the Republican-controlled House overwhelmingly voted against a bill which would have repealed the state's 2-year-old gay marriage law. The measure, sponsored by Rep. David Bates, sought to end gay nuptials in the state and give gay and lesbian couples civil unions in its place. At the time, nearly 2,000 gay couples had tied the knot.
