"At first glance, Rudolph W. Giuliani should be an appealing presidential candidate for observant Roman Catholics. The grandchild of Italian immigrants, Mr. Giuliani went to Catholic schools, considered joining the priesthood, and as mayor of New York battled a museum that exhibited a painting of the Virgin Mary adorned in elephant dung.
But church leaders say they are frustrated by prominent Catholic politicians like Mr. Giuliani who argue that while they are personally opposed to abortion, they do not want to impose their beliefs on others."
