morals, compromise, absoluteness, and power.

David asks some provocative questions in the following excerpt from his comment in this thread

What struck me most forcefully about this is that politics — unlike morals — is all about compromise. I was never clear on how people who wed their faith to moral absolutes could ever come to terms with a system that essentially forces people to trade what they “believe” for what they can get. But it was doubly ironic to hear the church pastor advocating for such compromise so that Christians could maintain their role in deciding the secular power structure.

But it also made me wonder anew: What place should morals and a moral agenda have in the selection of the President of the United States? What role should followers of Christ take in defining that moral position — based on the teachings of Jesus? Should believers in the absoluteness of some truths ever compromise them in order to maintain their place in a power structure?
