Catholics cannot vote for Obama

Teaching of the Catholic Church

Catechism of the Catholic Church # 2273

The inalienable right to life of every innocent human individual is a constitutive element of a civil society and its legislation:
"The inalienable rights of the person must be recognized and respected by civil society and the political authority. These human rights depend neither on single individuals nor on parents; nor do they represent a concession made by society and the state; they belong to human nature and are inherent in the person by virtue of the creative act from which the person took his origin. Among such fundamental rights one should mention in this regard every human being's right to life and physical integrity from the moment of conception until death."
“The moment a positive law deprives a category of human beings of the protection which civil legislation ought to accord them, the state is denying the equality of all before the law. When the state does not place its power at the service of the rights of each citizen, and in particular of the more vulnerable, the very foundations of a state based on law are undermined.... As a consequence of the respect and protection which must be ensured for the unborn child from the moment of conception, the law must provide appropriate penal sanctions for every deliberate violation of the child's rights.”( Donum Dei)

Doctrinal Note on some questions regarding the participation of Catholics in political life (Congregation for the Doctrine of the Faith, Cardinal Ratzinger. Note approved and ordered by Pope John Paul II. January 16th 2003)

Catholics, in this difficult situation, have the right and the duty to recall society to a deeper understanding of human life and to the responsibility of everyone in this regard. John Paul II, continuing the constant teaching of the Church, has reiterated many times that those who are directly involved in lawmaking bodies have a «grave and clear obligation to oppose» any law that attacks human life. For them, as for every Catholic, it is impossible to promote such laws or to vote for them.

Compendium of the Social Justice by the Pontifical Council for Justice and Peace (June 2004)

When — concerning areas or realities that involve fundamental ethical duties — legislative or political choices contrary to Christian principles and values are proposed or made, the Magisterium teaches that "a well-formed Christian conscience does not permit one to vote for a political programme or an individual law which contradicts the fundamental contents of faith and morals".
Faced with the many situations involving fundamental and indispensable moral duties, it must be remembered that Christian witness is to be considered a fundamental obligation that can even lead to the sacrificing of one's life, to martyrdom in the name of love and human dignity.

Barack Obama’s position on abortion

(From http://my.barackobama.com/page/content/womenissues)

Supports a Woman's Right to Choose:
Barack Obama understands that abortion is a divisive issue, and respects those who disagree with him. However, he has been a consistent champion of reproductive choice and will make preserving women's rights under Roe v. Wade a priority as President. He opposes any constitutional amendment to overturn the Supreme Court's decision in that case.
