What's the point? There is no difference between voting for an atheist, a Christian or a Mormon. A person should vote the issues.
None of these are disqualifying elements, IMHO. I am in full support of the re-election of my Mormon state legislator.
Do I agree with him on everything? No -- he's rather more libertarian than I am. But I have yet to see another state representative as thoughtful as he is about ALL the issues brought forward.
