A leading religious conservative group in Iowa is asking the Republican presidential candidates to sign a pledge vowing marital fidelity and support for a same-sex marriage ban, according to The Brody File.
Any candidate refusing to sign the pledge would be ineligible for an endorsement from The Family Leader. The head of the group, former gubernatorial candidate Bob Vander Plaats, helped steer Mike Huckabee's Iowa caucus win in 2008.
Two major candidates for the GOP nomination have already signaled that Iowa will not be a major part of their overall strategy. Mitt Romney will not participate in next month's Iowa Straw Poll in Ames, while Jon Huntsman has said he is "not competing" in the Hawkeye State. Both Romney and Huntsman are Mormons who have taken moderate positions on some social issues.
The pledge could also be awkward for Newt Gingrich, who has acknowledged being unfaithful in his previous marriages.
