Six of the 15 Republicans running for president are Catholic. Five of them (the exception is former New York Gov. George Pataki) have often invoked their faith to justify their positions on abortion, homosexuality, and terminating life support. They’ve also chastised Catholics who dissent from the Vatican on these issues. Three months ago, speaking to a Christian audience, Jeb Bush derided the type of politician “whose moral convictions are so private, so deeply personal, that he refuses even to impose them on himself." Sen. Marco Rubio mocked liberals who “ignore multiple pronouncements of this pope on the definition of marriage and on the sanctity of life.”
