Candidates signing the "Marriage Vow"

Given all the controversy over Michele Bachmann's signing of the "Marriage Vow," I thought that it might be useful to actually read the original text.

 Personal fidelity to my spouse.
 Respect for the marital bonds of others.
 Official fidelity to the U.S. Constitution, supporting the elevation of none but faithful constitutionalists as judges or justices.
 Vigorous opposition to any redefinition of the Institution of Marriage – faithful monogamy between one man and one woman – through statutory-, bureaucratic-, or court-imposed recognition of intimate unions which are bigamous, polygamous, polyandrous, same-sex, etc.
 Recognition of the overwhelming statistical evidence that married people enjoy better health, better sex, longer lives, greater financial stability, and that children raised by a mother and a father together experience better learning, less addiction, less legal trouble, and less extramarital pregnancy.
 Support for prompt reform of uneconomic, anti-marriage aspects of welfare policy, tax policy, and marital/divorce law, and extended “second chance” or “cooling-off” periods for those seeking a “quickie divorce.”
 Earnest, bona fide legal advocacy for the Defense of Marriage Act (DOMA) at the federal and state levels.
 Steadfast embrace of a federal Marriage Amendment to the U.S. Constitution which protects the definition of marriage as
between one man and one woman in all of the United States.
 Humane protection of women and the innocent fruit of conjugal intimacy – our next generation of American children –
from human trafficking, sexual slavery, seduction into promiscuity, and all forms of pornography and prostitution,
infanticide, abortion and other types of coercion or stolen innocence.
 Support for the enactment of safeguards for all married and unmarried U.S. Military and National Guard personnel,
especially our combat troops, from inappropriate same-gender or opposite-gender sexual harassment, adultery or intrusively intimate commingling among attracteds (restrooms, showers, barracks, tents, etc.); plus prompt termination of military policymakers who would expose American wives and daughters to rape or sexual harassment, torture, enslavement or sexual leveraging by the enemy in forward combat roles.
 Rejection of Sharia Islam and all other anti-woman, anti-human rights forms of totalitarian control.
 Recognition that robust childbearing and reproduction is beneficial to U.S. demographic, economic, strategic and actuarial
health and security.
 Commitment to downsizing government and the enormous burden upon American families of the USA‟s $14.3 trillion
public debt, its $77 trillion in unfunded liabilities, its $1.5 trillion federal deficit, and its $3.5 trillion federal budget.
 Fierce defense of the First Amendment‟s rights of Religious Liberty and Freedom of Speech, especially against the
intolerance of any who would undermine law-abiding American citizens and institutions of faith and conscience for their adherence to, and defense of, faithful heterosexual monogamy.

The Washington Post for example claims:

Rep. Michele Bachmann (R-Minn.) is the first presidential candidate to sign a pledge written by a socially- conservative advocacy group in Iowa that, among other things, endorses the view that homosexuality is a choice rather than a biological trait. . . .

Yet, I can't find anything in the pledge that makes that claim. But take this statement in the accompanying document: "No peer-reviewed empirical science or rational demonstration has ever definitively proven, nor even has shown an overwhelming probability, that homosexual preference or behavior is irresistible as a function of genetic determinism or other forms of fatalism." But it is a long way from saying that existing evidence doesn't prove something and saying that there is no relationship. In any case, I think that the key point here is "irresistible" and you could even have a genetic predisposition towards something, even a strong disposition, but that is not the same as saying that it is "irresistible."
