My conclusions about the chances of an orthodox (in the general sense not Eastern Orthodox) Christian revival in the US are based on history and understanding the memetic engine that produced said history.

Theology in the US became a market based when the colonies / states disestablished their churches. This didn't happen all at once, but the idea was baked into the US Constitution assuring its eventual victory, barring amendment.

Market based theologies are like dime novels or, for a more modern example, hit television shows. They give the people what they want. What do men born in sin want...

You see where I am going with this.
