"The essential issue in this race is freedom," said Senator Rick Santorum in a triumphant speech on the eve of his strong second-place showing in the Iowa caucus.

But what kind of freedom is Santorum talking about? Reason.tv caught up with Santorum at a campaign stop at Des Moines Christian Assembly in Urbandale, Iowa, where he spoke to schoolchildren and their parents about the importance of electing a leader who will promote good social values to the citizens.

"Why wouldn't leaders in this country stand up and promote marriage?" asked Santorum. "Stop, in any way they could, the sexual promiscuity that goes on that leads to out-of-wedlock births."

Santorum picked up the endorsement of Jim Bob Duggar, patriarch of the Duggar family (of TLC's "19 Kids and Counting"), who sung the national anthem to kick off the festivities. Also in attendance was social conservative activist and founder of the Faith and Freedom Coalition Ralph Reed. Reed has not endorsed a candidate in the race yet, but he stresses that social conservatism remains a core value to GOP voters.

"You're not going to do well, either in Iowa or beyond, if you're not pro-marriage, pro-family, and pro-life," said Reed. "Whether you're coming from a libertarian perspective or a more traditional conservative perspective."

If GOP voters want candidates who are ready to fight the culture war, Santorum seems ready to deliver.

"I love it when the Left, and the president, says, 'Don't try to impose your values on us, you folks who hold your Bibles in your hand and cling to your guns,'" Santorum said. "It's equally imposing values. It's just in their world, if it's Biblically based or religiously based, it's out. If it's anything else, bring it on."
