If people voted on the basic religious values their churches promote, there would never be a Democratic president... ever.
The fact is, though, that we constantly vote for people who share nothing of the world view of religion. Catholics vote for pro-choice candidates in droves. Little old African American ladies who never miss church voted for someone like Bill Clinton, and by a huge margin. Some of the most devout religious people in the US are Hispanics, and they consistantly vote for morally liberal candidates.
For that reason I think we should look at all the hubbub about the religious beliefsof people in public service. It is damn near impossible to get a Catholic approved as a federal judge because the activists in congress think their anti-abortion, pro "values" bent will color their judgements.
If the average American can vote with no fear of religious conflict, it seems like we could let judges and other government leaders do the same.
