The weirdly named Iowa hate group “The Family Leader” came out with a purity pledge a few months ago for GOP presidential candidates to sign. Michele Bachmann and Rick Santorum were the only ones to sign the anti-gay document, and we all know where their campaigns are now. Rick Perry’s campaign should basically be over at this point, so he’s gone ahead and signed the wingnut thing:

The pledge advocates several issues, including the Defense of Marriage Act, personal fidelity to the signee’s spouse, appointment of “faithful constitutionalists” as judges, and reformation of anti-marriage elements in divorce, tax and welfare laws.

Family Leader head Bob Vander Plaats has said signing the pledge will be a prerequisite for the group’s endorsement, one coveted among candidates seeking to nab the evangelical vote.

Minnesota Congresswoman Michele Bachmann and former Pennsylvania Sen. Rick Santorum have both signed the vow. Former House Speaker Newt Gingrich has indicated he would sign it if he could make a few modifications.

Ha ha, he probably doesn’t like the part about “being faithful to spouses who are currently having cancer.”
