If a candidate is pro-choice, you may not agree with a candidate’s stance on abortion, but may agree with them on other issues - are those issues proportionate enough to vote for them, if they are pro-choice?
Bishop Robert J. Carlson:
If one had a properly formed conscience admitting the grave evil of abortion and euthanasia, as the Church teaches, and does not share a candidates stand in favor of abortion and euthanasia, but votes for the candidate for other reasons, it is considered remote material cooperation which can be permitted, Cardinal Ratzinger states, if proportionate reasons are present, e.g., the candidate would limit abortions.

Archbishop John J. Myers:
What are ‘proportionate reasons’? To consider that question, we must first repeat the teaching of the church: The direct killing of innocent human beings at any stage of development, including the embryonic and fetal, is homicidal, gravely sinful and always profoundly wrong . . . .
What evil could be so grave and widespread as to constitute a “proportionate reason” to support candidates who would preserve and protect the abortion license and even extend it to publicly funded embryo-killing in our nation’s labs?
Certainly policies on welfare, national security, the war in Iraq, Social Security or taxes, taken singly or in any combination, do not provide a proportionate reason to vote for a pro-abortion candidate.

Archbishop Burke:
The archbishop told a reporter that he believes Catholics could vote for a politician who supports abortion rights as long as that’s not the reason they are voting for the candidate, and they believe the politician’s stance on other moral issues outweighs the abortion issue.
“That is called remote material cooperation and if the reasons are really proportionate, and the person remains clear about his or her opposition to abortion, that can be done,” the archbishop told the Post-Dispatch.
“The sticking point is this - and this is the hard part,” Archbishop Burke was quoted as saying. "What is a proportionate reason to justify favoring the taking of an innocent, defenseless human life? And I just leave that to you as a question. That’s the question that has to be answered in your conscience. What is the proportionate reason?
One of the reasons the bishop did not discuss this point in June is because “it is difficult to imagine what that proportionate reason would be,” he said.

Fr Stephen F. Torraco:
Fr. Stephen F. Torraco, PhD., explains that “‘Proportionate reasons’ has a very specific meaning in Catholic moral teaching. A proportionate reason [to vote for pro-abortion candidates] would be the desire to avoid supporting an equally grave or graver intrinsic evil, and not just for any reason at all. An intrinsic evil is an evil that cannot be morally justified for any reason or set of circumstances. So, for example, capital punishment is not a proportionate reason. A candidate’s stand on economic issues is not a proportionate reason.”

George Weigel:
But the crucial questions – largely missing from press coverage of the cardinal’s letter – remain: When is this morally justifiable? What are the “proportionate reasons” that would lead a pro-life voter to conclude that a pro-abortion candidate’s unacceptable position on the life issues can, in effect, be bracketed?
I can imagine one such situation: when the choice is between two pro-abortion candidates, and a voter opts for the pro-abortion candidate of a pro-life party in order to keep that pro-life party in control of Congress. That was the case in my own Congressional district for years. But that is not the situation that Catholic voters face in the current presidential contest or in most Congressional races

Fr Stephen F Torraco:
14. Is it a mortal sin to vote for a pro-abortion candidate?
Except in the case in which a voter is faced with all pro-abortion candidates (in which case, as explained in question 8 above, he or she strives to determine which of them would cause the let damage in this regard), a candidate that is pro-abortion disqualifies himself from receiving a Catholic’s vote. This is because being pro-abortion cannot simply be placed alongside the candidate’s other positions on Medicare and unemployment, for example; and this is because abortion is intrinsically evil and cannot be morally justified for any reason or set of circumstances. To vote for such a candidate even with the knowledge that the candidate is pro-abortion is to become an accomplice in the moral evil of abortion. If the voter also knows this, then the voter sins mortally.
