What role should the personal faith of a President play in his/her decision-making?

This recent debate just sort of set me off. The people of America are becoming so ignorant. What role should the personal faith of a President play in his/her decision-making? That question is absolutely ridiculous!! Asking that is just like asking what role should personal moral have in decision-making? Yes, the stupid people who have no idea what they are talking about will quote the "separation of church and state" that is written in The Constitution, and yes The Constitution does call for an "iron curtain" between the Church and The State, that merely means that the government should have nothing to do with establishing a religion for this country!! The way kids are raised is through their parents opinions on how they should raise their children. These opinions are rooted in moral, moral is formed from a belief in the right thing to do. Im pretty sure that comes from religion or lack of. What else tells us the right and wrong thing to do? Well maybe some say the thousands of years we have existed and our experiences we have learned from all that yada yada, but for thousands of years people have had some sort of religion, and it has revolutionized into the religions of today's world. As a christian we are called to only do something that Jesus would do, and I am pretty sure that other religions preach around the same deal.

Thinking that the personal faith of a president ever will have nothing to do with his or her decision making is like thinking the president will one day blind fold him or herself and play "pin the tail on the decision"
