NOM's Maggie Gallagher says Minnesota Rep. Michele Bachmann's opposition to gay marriage will help her win the Iowa caucuses.

Bachmann and former Pennsylvania Senator Rick Santorum are the only 2012 presidential candidates to have signed the Iowa-based Christian conservative group The Family Leader's anti-gay marriage pledge.

The 14-point pledge also suggests that being gay is a choice and a public health risk.

In addition, Michele Bachmann's husband, Marcus, has denied claims that Bachmann & Associates, the family's Christian counseling center mentioned by Mrs. Bachmann as a job creator, seeks to “cure” gay people.

In a story published Monday at, gay activists say Michele Bachmann's anti-gay rhetoric will derail her candidacy.

“We're going to be looking for opportunities to get her record and her rhetoric out there,” Michael Cole-Schwartz, the communications director for the Human Rights Campaign (HRC), told the website.

Voters in both parties will view “any candidates who espouse those kind of beliefs [as] living in the Twilight Zone,” he added.

But Gallagher, the chair of the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, warned that the attacks would backfire.

“The more that they attack Michele Bachmann on these grounds, the better her chances of winning the Iowa caucuses are,” said Gallagher. “The Iowa base is extremely upset about same-sex marriage and I don't think they're going to look kindly on these attacks.”
