Being pro-abortion is an automatic disqualifer, just as most reasonable citizen would say is the case with one who is a racist. In other words, not matter how NOBEL his positions on a host of other issues, he or she has proves himself to be serious flawed in a fundamental or foundational way. Back in 1974 the Holy See spoke out CLEARLY on this issue: Practically speaking, that means a refusal to support pro-abortion politicians. Is this "single-issue voting"? Let the distinguished ethicist Germain Grisez reply to that objection: "Single issue voting is irrational," he says. But, he continues, "the proper standards for evaluating candidates for public office are competence and character, [and] any individual seeking public office who supports the legality -- much less the public funding -- of abortion manifests a character which makes him or her unfit for public office."
