DANVILLE, Ky. (AP) — Vice presidential hopefuls Joe Biden and Paul Ryan say their Catholic faith informs their public policy decisions, but they come down on different sides of the abortion debate.

Biden, President Barack Obama's running mate, said his Catholicism teaches that life begins at conception but that he would not impose that belief on people of other faiths. Ryan, the running mate of GOP challenger Mitt Romney, said he opposes abortion but that the policy of a Romney administration would include exceptions in cases of rape, incest or when the life of the mother is at stake.
