Former Arkansas Governor Mike Huckabee compared gay marriage to polygamy Tuesday.

Appearing on CBS News' webshow @katiecouric, Huckabee told Katie Couric that if you alter marriage to include gay couples “then there is really no limit” to how it might be defined and suggested polygamy would soon follow.

Huckabee, a former Baptist minister, also does not believe gays should be allowed to serve in the military and supports a constitutional amendment defining marriage as a heterosexual union. He is the presidential choice of social conservatives who attended this year's Value Voters Summit, the annual conservative meet up sponsored by the Family Research Council (FRC), an ardent opponent of gay and lesbian rights. Surprisingly, former Alaska Governor and 2008 Republican vice presidential candidate Sarah Palin trailed in fourth place.

While conceding that children raised in single parent households could grow up to be “healthy and strong,” he insisted that children are “best developed when they see healthy male and female figures,” then added, “children need a mom and a dad to give them that balance.”

Hucakabee, who appeared on the program to promote his new book A Simple Christmas: Twelve Stories that Celebrate the True Holiday Spirit, said that he does not oppose gay marriage but is in favor of traditional marriage.

“Can we change it to multiple spouses?” he rhetorically asked. “If not, why not? You know, I hear people say, 'Well, what would be wrong?' What would be wrong, then, with a man having two or three or six or seven wives? Or a woman having six or seven husbands all at the same time?”

“If enough people believe that we should have – I'll just use the illustration of polygamy – then we should accommodate that. Otherwise, are we being just as bigoted and intolerant and lacking compassion 'cause we don't promote and accept and put a sanction on polygamy?” he asked. “I don't think so.”
