There is no element of the common good, no morally good practice, which a candidate may promote and to which a voter may be dedicated, which could justify voting for a candidate who also endorses and supports the deliberate killing of the unborn, euthanasia or the recognition of a same-sex relationship as a legal marriage. The respect for the inviolable dignity of innocent human life and for the integrity of marriage and the family are so fundamental to the common good that they cannot be subordinated to any other cause, no matter how good it may be.
-- Archbishop Raymond Burke, The Teachings of the Catholic Church, National Catholic Prayer Breakfast, May 8, 2009
