Ahead of South Carolina's primaries Republican presidential hopeful Mike Huckabee goes on the offensive against gays, linking gay marriage to bestiality

In a telephone interview with Beliefnet's Steven Waldman and  Dan Gilgoff, and posted on the Beliefnet website, Mike Huckabee once again asserted his opposition to gay marriage and compared the idea to bestiality.

"Marriage has ... as long as there's been human history, meant a man and a woman in a relationship for life. Once we change that definition, then where does it go from there?" he asked his interviewers.

"Well, I don't think that's a radical view, to say we're going to affirm marriage. I think the radical view is to say that we're going to change the definition of marriage so that it can mean two men, two women, a man and three women, a man and a child, a man and animal," he added.

The former Arkansas governor said he would amend the Constitution to conform to the Bible on issues where it is being "challenged": marriage and abortion.  "I support both the human rights amendment and a marriage amendment, and the reason that I do is because I think we need to codify in our Constitution that which has been acceptable and accepted view of what life and what marriage means. Frankly, if it weren’t being challenged, it wouldn’t be necessary. But it is being challenged. Now you have states that are passing same-sex marriage laws or civil union laws."

Huckabee, a former Baptist pastor, is running for the Republican presidential nomination.  The former Arkansas governor, 52, was born in Hope, Arkansas -- the birthplace of former president Bill Clinton.  He won the Iowa Republican caucuses earlier this month and hopes to win in today's South Carolina primaries by appealing to a large bloc of evangelicals.
