Brian Brown, president of the National Organization for Marriage (NOM), has described Tuesday's election results as a victory for opponents of marriage equality.

“Marriage won an overwhelming victory,” Brown said in a blog post. “In red states and blue, candidates who supported marriage as the union of one man and one woman won election and those who didn't were rejected by voters. The Republican Party should take note that their nominees who favored gay 'marriage' were opposed by NOM and they were resoundingly defeated.”

This year, NOM launched a super PAC, the NOM Victory Fund, which targeted the re-election campaigns of Democratic Senators Mark Pryor of Arkansas, who lost to Tom Cotton, and Kay Hagan of North Carolina, who lost to Thom Tillis.

The group attacked Pryor's opposition to marriage equality, which NOM called unconvincing, and linked Hagan to a federal judge who struck down North Carolina's restrictive marriage ban.

NOM also opposed two Republican House candidates who are openly gay, Carl DeMaio of California and Richard Tisei of Massachusetts, and one Republican Senate candidate who backed marriage equality, Monica Wehby of Oregon.

Tisei and Wehby lost on Tuesday, while DeMaio's race against Democrat Scott Peters remains too close to call.

NOM said that it opposed Tisei and DeMaio because of their support for same-sex marriage, not their sexual orientation.

“It's time for the GOP elite and consultant class to wake up and realize that marriage is a winning issue, in red states and blue,” Brown said. “Traditional marriage amendments have received 50 million votes across America, and candidates who embraced marriage this election won, while Republicans who rejected marriage were themselves rejected. The election results tonight were a stunning rebuke of those who wish to redefine marriage. We look forward to working with Congress to advance the cause of marriage.”

Brown has yet to comment on a federal ruling striking down Kansas' marriage ban, which was handed down Tuesday.
