I certainly don't trust politicians to do anything at all. However, politicians will make moral choices when moral people force them to do so (in a democracy, such as ours). I agree with you in that we do live in an amoral society because people have turned away from God. But it is incumbent on those who have not turned away from God to vote in such as way as to reflect moral choice, and to influence politicians to make moral choices. I believe in God. I believe that things like partial birth abortions are just pure baby-killing. To me, voting against an abomination like that is far more important than the tax rate or the state of the economy. It is the very least I can do to vote that way. Those who believe in God and that abortion is murder should not flinch from the fight to try to save babies. In the same way, many Christians of all stripes fought to end slavery, though the politicians in general at that time couldn't find the moral strength to do so.
