We often face choices in which none of the candidates is fully aligned with our Church’s teachings. Too often, voter choices seem to fall into the “lesser-of-two-evils” category. The bishops address this dilemma in Forming Consciences for Faithful Citizenship:
“Catholics often face difficult choices about how to vote. This is why it is so important to vote according to a well-formed conscience that perceives the proper relationship among moral goods. A Catholic cannot vote for a candidate who favors a policy promoting an intrinsically evil act, such as abortion, euthanasia, assisted suicide, deliberately subjecting workers or the poor to subhuman living conditions, redefining marriage in ways that violate its essential meaning, or racist behavior, if the voter’s intent is to support that position. In such cases, a Catholic would be guilty of formal cooperation in grave evil. At the same time, a voter should not use a candidate’s opposition to an intrinsic evil to justify indifference or inattentiveness to other important moral issues involving human life and dignity.
“There may be times when a Catholic who rejects a candidate’s unacceptable position even on policies promoting an intrinsically evil act may reasonably decide to vote for that candidate for other morally grave reasons. Voting in this way would be permissible only for truly grave moral reasons, not to advance narrow interests or partisan preferences or to ignore a fundamental moral evil.
“When all candidates hold a position that promotes an intrinsically evil act, the conscientious voter faces a dilemma. The voter may decide to take the extraordinary step of not voting for any candidate or, after careful deliberation, may decide to vote for the candidate deemed less likely to advance such a morally flawed position and more likely to pursue other authentic human goods.
“In making these decisions, it is essential for Catholics to be guided by a well-formed conscience that recognizes that all issues do not carry the same moral weight and that the moral obligation to oppose policies promoting intrinsically evil acts has a special claim on our consciences and our actions. These decisions should take into account a candidate’s commitments, character, integrity, and ability to influence a given issue. In the end, this is a decision to be made by each Catholic guided by a conscience formed by Catholic moral teaching” (Forming Consciences for Faithful Citizenship, nos. 34-37).
