I don't buy this. I saw Abp. Burke on EWTN recently, and he made it clear that only matters of life could ever qualify as "proportianate reasons."
In that scenario, a Catholic who personally opposes abortion rights, votes for a candidate who supports abortion rights "for what are called proportionate reasons," he said.
In other words, each individual Catholic must weigh all the moral issues a candidate stands for alongside the candidate's position on abortion rights.
"And that is called remote material cooperation and if the reasons are really proportionate, and the person remains clear about his or her opposition to abortion, that can be done," Burke said.
So, a Catholic who does not support abortion rights can vote for a candidate who does support abortion rights without fear of committing a grave sin.
"The sticking point is this - and this is the hard part," said Burke. "What is a proportionate reason to justify favoring the taking of an innocent, defenseless human life? And I just leave that to you as a question. That's the question that has to be answered in your conscience. What is the proportionate reason?"
