Brian Brown, president of the National Organization for Marriage (NOM), on Thursday predicted the state count on gay marriage isn't about to grow much in the short term.

In an interview with USA Today, Brown, who helms the nation's most visible organization opposed to such unions, said efforts in Minnesota, Illinois, New Jersey and Oregon would fail.

Brown made his remarks just hours before the Rhode Island House gave its final approval to a marriage bill and independent Governor Lincoln Chafee signed it into law.

Brown appeared hesitant to predict an outcome in Delaware, where a final vote on a bill is set to take place next week.

“In Delaware, it's going to be a tough fight and I think it's going to be a close vote.”

In Illinois “they would have called the bill if they had the votes,” Brown said of a proposed measure in the state.

“There's been tremendous opposition from the African-American community to redefining marriage. The president, Rahm Emanuel, others are pushing to try and get the votes, but right now it's not there. And I think again that shows you that this myth that somehow same-sex marriage is inevitable is just a myth.”

“We have all of the cultural powers that be trying to bring forth this new edict that this is now the norm, this is what good Americans believe. That if you disagree with this idea, you're discriminating, or this is bigotry.”

“I think we have a very good chance of winning in Minnesota,” he said, referring to a bill in the state which awaits action in both legislative chambers.

An expected attempt to override Republican Governor Chris Christie's veto in New Jersey doesn't stand a chance, Brown said.

Brown also predicted defeat for an effort to legalize marriage equality with a referendum in Oregon.

“We'll have another statewide fight and the people will be able to vote. I think we can win that vote,” he said.
