For the National Organization for Marriage (NOM) 2012 proved to be a rocky year.

While the nation's most vociferous opponent of gay marriage was successful in getting a constitutional amendment limiting marriage to heterosexual couples approved in North Carolina, little else went the group's way.

In an end-of-the-year blog post at, Carlos Maza highlighted some of NOM's biggest missteps in 2012.

An important story which went largely unnoticed was NOM's shrinking support from donors. The Human Rights Campaign (HRC) revealed that “just two donors were responsible for funding 75 percent of the anti-gay group.” Federal tax documents from 2011 also showed that NOM's budget had declined from the previous year – from $9.1 million to $6.2 million.

In New York and New Hampshire, NOM has been unable to follow through on its pledge to reverse marriage equality gains. In New Hampshire, NOM backed legislative efforts to repeal the state's marriage law. But a Republican controlled House stunned NOM by rejecting the plan, with more than 100 GOP lawmakers voting against the effort. Democrats regained control of the House on November 6, dashing NOM's hopes for another try. In New York, NOM's campaign to “elect pro-marriage majorities” resulted in just two seats flipping in their favor.

NOM's boycott efforts also largely failed. NOM pursued efforts to hit Starbucks and General Mills in their pocketbooks after each company sided with marriage equality supporters. Seattle-based Starbucks endorsed an effort to legalize gay nuptials in Washington state, while Minneapolis-based General Mills opposed a measure to ban it in Minnesota. A Starbucks representative said the coffee giant was “not seeing any impact” as a result of the boycott. And praise for their stands outpaced opposition.

NOM's largest defeats came on November 6, when marriage equality supporters won referendums in four states and President Barack Obama won reelection. Voters in three states – Maine, Maryland and Washington state – were the first to approve marriage rights for gay couples at the ballot box. And Iowa voters decided to keep state Supreme Court Justice David Wiggins, for whose ouster NOM had campaigned over his participation in a 2009 ruling legalizing gay nuptials in the state.
