Neither of us has endorsed Donald Trump. Both of us have been intensely critical of him on issues of personal character and, in some cases, public policy. We do not claim, as some have claimed, that Catholics and other pro-life citizens have an obligation to cast their ballot for him. The premises of the argument against abortion do not by themselves compel such a stance. People who share the view that the abortion license is a profound injustice on a massive scale that must be resolutely opposed can reach different conclusions about whether Trump deserves their vote.30
If, however, the considerations we have adduced in this essay are sound, they practically preclude a vote for Biden. If one acknowledges the gravity, scale, and scope of the injustice of abortion, and of a legal regime that denies to an entire class of human beings the most basic of human rights, thus exposing them to lethal violence, then it is hard to imagine what proportionate reasons there could be for joining one’s will to the desire of a supporter of it for great political power.
