Americans United for Separation of Church and State has posted an article on their blog regarding the Presidential hopefuls and how their religions come into play in voter decision-making.
Americans United says:
If you want to know where a candidate stands on an issue, ask him or her. Don’t assume the candidate’s religious affiliation will give you the answer. The Roman Catholic Church opposes abortion in all instances, including cases of rape and incest. Few Catholic office-holders take such a hard line; many are pro-choice.
