The basis of this country's rule of law is secular philosophy, not religious ideology. However, I don't expect a politician to ignore his or her beliefs, nor do I expect him or her to stick strictly to a humanist approach.
Most of us aren't "afraid of influence." I'm apprehensive of the black-and-white Christian distinctions of good and evil, and religious justification of political action. I don't want a president who
kills people because God told him to.
