What does that prove? He's a Christian, and he says his relationship with Christ inspires him and makes him stronger as a leader. He also has said that he was chosen by God, and that would be Christ. He's not saying that he was chosen by God to impose Christianity on Americans. He's really careful about that. He's gotten even more careful in his second term.
I strongly disagree, in the case of President Bush as well as Moore.
Those who believe in freedom of conscience will oppose attempts by people like you to impose religious tests to weed out those you consider "zealots" from the government.
