This seems to be Howard Finemans big question. Hes not sure, though, as he puts it, the promotion of the candidacy of pro-life Democrat Bob Casey, Jr. to challenge conservative Catholic stalwart Rick Santorum suggests that the Democrats "didn’t want to have to take on the GOP, the White House and the Church at the same time—at least on the issue of abortion—in a state where the electorate is nearly 50 percent Catholic."
By the by, Fineman also offers a misleading characterization of then-Cardinal Ratzingers advice to Catholic voters in the last election cycle. Heres Fineman:
In his writings and interviews, the former Cardinal Ratzinger declared that politicians who support abortion rights should be turned away—and that it is a sin for Catholic voters to support a pro-choice candidate if their main reason for doing so is the candidate’s abortion views.
A Catholic would be guilty of formal cooperation in evil, and so unworthy to present himself for Holy Communion, if he were to deliberately vote for a candidate precisely because of the candidate’s permissive stand on abortion and/or euthanasia. When a Catholic does not share a candidate’s stand in favour of abortion and/or euthanasia, but votes for that candidate for other reasons, it is considered remote material cooperation, which can be permitted in the presence of proportionate reasons.
Gee, this means that Catholics are permitted to use their prudence in weighing the pros and cons of candidates, so long as they do not make approval of abortion and euthanasia the principal reason for supporting a candidate, a much more nuanced and subtle position than Fineman wants to attribute to the new Pope.
