Brian Brown, the president of the National Organization for Marriage (NOM), has said losing marriage equality issues in four states on Tuesday won't affect his organization.

In remarks to, Brown also stated that he believes Republican presidential candidate Mitt Romney is a solid opponent of gay marriage, despite not mentioning the issue much on the campaign trail since he secured the nomination.

“Mitt Romney supports marriage as the union of a man and a woman,” Brown said, adding that as governor he was strongly opposed to the Massachusetts Supreme Court's 2004 ruling legalizing marriage for gay and lesbian couples: “He was very strong, he spoke at rallies, he was strong the whole way through. Were there some people that were disappointed that he didn't just, by fiat, say, 'We're not going to obey the judges!'? There are always people that do that, but in the real world, Romney went above and beyond.”

“He's always been a strong supporter of protecting marriage, and he was an early signer of [NOM's] Marriage Pledge. We obviously believe that he will follow through in his commitment; I don't see why anyone would say otherwise.”

While Brown discredited polling which indicates increasing support for gay nuptials, he also appeared to concede that his group could lose big on Tuesday.

“This makes clear that the people of this country know that marriage is the union of a man and a woman, and all this talk about somehow the country turning is absolutely false, and that protecting marriage is a winning issue. If we lose one, that would still be the same.”

“It becomes harder if it's two, three or four, but I don't think that's going to happen.”

If it happens, Brown added, that would “be a bad day, but we live to fight on. We fight, day in and day out. We've been down before, we've come back. It's not going to change anything as far as our commitment to the battle.”

Later he added, “This is never over. We're not giving up any ground. Ever.”

Brown also predicted a shift away from the states and towards the federal government if the Supreme Court strikes down California's gay marriage ban, Proposition 8.

“There will be a Federal Marriage Amendment fight if the court does take the Perry case and then rules against us,” he said.
