The National Organization for Marriage (NOM) has taken out a newspaper ad criticizing Republican lawmakers who voted against repealing New Hampshire's 2-year-old gay marriage law.

Roughly 100 Republican House members last month voted against the measure sponsored by GOP colleague David Bates.

The full page ad, which lists the names of all the Republicans who voted against repeal, states: “The cause of marriage was betrayed by the Republican state representatives listed below. They led voters to believe they supported traditional marriage, but instead voted in favor of same-sex marriage. They stood with Democrats from New York who created and funded a phony 'Republican' front-group. They stood with interests who want to rip traditional marriage from the GOP platform. They stood against every major Republican candidate for president.”

“Contact the Republican legislators below and let them know how disappointed you are, and that you intend to hold them accountable for abandoning marriage.”

NOM President Brian Brown added in a statement: “In 2010, NOM spent over $1 million to elect pro-marriage candidates in New Hampshire. We intend to play a significant role in supporting candidates this year as well. We invite pro-marriage candidates of either party, Republicans and Democrats, to step up and run for office so that we can help elect a pro-marriage legislative majority in November. The people of New Hampshire support marriage as the union of one man and one woman, and we will not rest until the Legislature corrects the mistake that was made in 2009.”
