Here is an interesting article on the failure of the Christian Right political movement to truly proclaim the Gospel: God, the Gospel, and Glenn Beck.
A great quote from the article:
There is a liberation theology of the Left, and there is also a liberation theology of the Right, and both are at heart mammon worship. The liberation theology of the Left often wants a Barabbas, to fight off the oppressors as though our ultimate problem were the reign of Rome and not the reign of death. The liberation theology of the Right wants a golden calf, to represent religion and to remind us of all the economic security we had in Egypt. Both want a Caesar or a Pharaoh, not a Messiah.
