The Catholic Church is abundantly clear about its teaching on abortion and gay “marriage”. When it comes to voting:

I rule out any candidate who actively supports these issues regardless of their stand on other issues. 100% (2 votes)
I don’t let one or two issues determine my vote so I may or may not vote for such candidates, based on the totality of where they stand on multiple issues. 0% (0 votes)
My vote is my vote; the Church has no right to tell me who to vote for or not vote for. 0% (0 votes)

Total Votes: 2

Give others the chance to vote.
