Here is a summary of Fr Scott's article from the SSPX website, posted in 2020:
https://sspx.org/en/news/catholic-morally-obligated-vote-lesser-two-evils-24855Summarized:
- Pope Pius XII decreed that there is a moral imperative (duty) for Catholics to vote in elections.
- In the United States, our choices are no longer between Catholic and non-Catholic.
- In practice, it generally comes down to the question of whether or not it is obligatory or permissible to vote for a "lesser of two evils"
- In such a case, there can be no obligation to vote, for all the reasons mentioned by Pope Pius XII below no longer apply.
- it is permissible to vote in such a case, provided that one can be sure that there truly is a lesser evil, and that there is a grave reason to do so,
There is also another article presented there which was also from the 2007 Angelus but no author is specified:
Can a Catholic vote for a candidate who condones initiatives not in accord with the moral law?
Originally published in August 2007 issue of The Angelus
Summarized:
- It is sinful for a Catholic to vote for a candidate who claims to be Catholic, but who is not Pro-Life (abortion, euthanasia, ɧoɱosɛҳųαƖ unions)
- However, Catholics are not morally obliged, in any way, to vote for the opponent of the above candidate.
- Catholics are only required to vote for candidates who are solidly Catholic
Article:
The Catholic Church does not tell Catholics to avoid all involvement in politics simply because there is injustice, greed, ambition, just to mention some of the evils involved. The Church teaches us that all our involvement in politics ought to be motivated, inspired, and directed by the Church’s social teachings, and in particular by the Social Kingship of Our Lord Jesus Christ. Voting, as well as involvement in political campaigns, must have as its ultimate motive these higher, supernatural principles, that the law of God, the Ten Commandments, and the rights of the one true Church be acknowledged publicly in society.
Manifestly, we are presently very far removed from achieving these aims. It does not mean that we should do nothing. It does mean, however, that whatever we do will necessarily involve the toleration of many evils, which we in no way desire or will. However, it can be permissible to tolerate the lesser of two evils for a proportionate reason, and such toleration can be for the common good, precisely because it is the lesser of two evils. Thus, it is possible to vote or even campaign for a candidate whose platform contains evils with which we do not agree. Everything depends upon a hierarchy of the most important values and issues taking priority over lesser ones.
For a Catholic, there can be no doubt that the issues that take the highest priority must be the moral issues, and not personal or economic issues. The whole continuation of society as we know it depends upon this, and those who deny the most basic principles of the natural order are bringing about an unheard of perversion. Consequently, it is permissible and prudent to vote on the one single issue of proscribing abortion, or forbidding same-sex marriages, or putting an end to euthanasia, or freedom of the Catholic Church to run educational institutions. All of these issues are of the utmost importance. Consequently, it would be permissible and prudent to vote for a candidate who promotes an unjust war, on the basis of one or other of these issues. Consequently, it is likewise permissible to vote for a candidate who is known to be a Freemason, although Fɾҽҽmαsσɳɾყ is an evil society condemned by the Church and opposed to the Catholic Church, if he maintains an important principle of the natural law such as the evil of abortion.
Lesser issues are also of moral importance, such as the justice or injustice of a particular war, or the paying of a just wage to employees, maintaining the right to private property by limiting government intervention, and so on. All other things being equal, one could vote on the basis of such issues. However, it would be wrong to vote for a candidate who has a correct position on one of these issues, but a perverse and wrong position on a more important issue.
Consequently, it would be manifestly immoral and sinful to vote for a candidate who pretends to be Catholic, but who in fact is pro-abortion, pro-gαy, or pro-euthanasia.
Voting in local and national elections can only be considered a moral obligation when the candidates propose a solidly Catholic, non-liberal platform that truly promotes the Social Kingship of Our Lord Jesus Christ. It is not obligatory to vote for a lesser evil, but simply prudent and permissible. However, it would certainly be obligatory to use the democratic process in place in the unlikely event that it could be used to introduce Catholic candidates who do not accept the propaganda of modern liberal democracy.
