Rick Santorum on Saturday told a crowd of conservative Republicans that he's finished making apologies for his opposition to gay marriage and blamed former Massachusetts Governor Mitt Romney for its legalization.

Speaking in Des Moines, Iowa at the Presidential Preference Convention hosted by the National Federation of Republican Assemblies, Santorum said he was being targeted in the media for his socially conservative stances.

“If you look at the debates, every single moral, cultural question has come to me first. I was in a conversation with Mike Huckabee the other day. I said, 'Mike, they're trying to Huckabee me.' They're trying to paint [me] into that box that you're the social conservative candidate and ask you all these social conservative questions.”

“Well as far as I'm concerned, bring it on … I am not ashamed for standing up for life, family and faith which are the foundation of our society.”

He then added that his GOP rival, Romney, was responsible for gay marriage being legal in 6 states and the District of Columbia.

“Guess who didn't rebuff the courts,” Santorum said, referring to the first state Supreme Court ruling to legalize gay marriage. “Governor Romney. Governor Romney issued those marriage licenses – ordered people to issue marriage licenses in contradiction to the constitution and the statutes of Massachusetts.”
