From Think Progress:
Tonight, Michele Bachmann became the first presidential candidate to sign a pledge created by THE FAMiLY LEADER, an influential social-conservative group in Iowa. By signing the pledge Bachmann “vows” to “uphold the institution of marriage as only between one man and one woman” by committing herself to 14 specifics steps. The ninth step calls for the banning of “all forms” of pornography. The pledge also states that homosexuality is both a choice and a health risk. You can read all the details of the pledge here.
