In response, permit me to explain what led to my own signature of the letter in question.
Readers of Catholics in the Public Square are no doubt aware that I have emphatically disagreed with Henry and those contributors at Vox Nova who supported Barack Obama throughout the 2008 election.
At the same time, to say Catholics shouldn’t have cast their vote for Obama is not the same thing as asserting that they were prohibited from doing so. This, at least, seems to be the conclusion drawn from the USCCB document “Forming Consciences for Faithful Citizenship”:
There may be times when a Catholic who rejects a candidate’s unacceptable position [on abortion] may 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.
Suffice to say I was among the those who did not believe a “grave moral reason” existed that warranted voting for Obama. And if some members of Vox Nova disagreed, I’ll give them the benefit of a doubt, and trust they thought about it as long and hard as my own decision to vote for Senator McCain.
