Tony Perkins, president of the Christian conservative Family Research Council (FRC), believes only a “very small minority” supports the legalization of gay marriage.

Perkins authored the marriage plank in the 2012 Republican Platform, which was ratified by Republicans meeting in Tampa on Tuesday.

The document supports a federal “constitutional amendment defining marriage as the union of one man and one woman” and “campaigns underway in several other states to” amend their constitutions to define marriage as a heterosexual union. The platform also criticizes President Barack Obama's decision to no longer defend the Defense of Marriage Act (DOMA) – the 1996 law which bars federal agencies from recognizing the legal marriages of gay and lesbian couples – in court.

In remarks to, Perkins disagreed with the Democratic Party's draft platform, which supports marriage equality.

“I think this is the year of contrast. This is the year of contrast when you look at the party platforms. The Republican Party has very strong language as it pertains to natural, traditional marriage. The Democratic Party [is] going the way of a very small minority in this country and embracing same-sex marriage, which undermines the 32 states that have voted on this – the 30 states that have constitutional amendments. I think that's in your face to those states that have constitutional amendments,” said Perkins. (The video is embedded on this page. Visit our video library for more videos.)
