Let's be honest, shall we? America is not going to become a socialist state, neither will it become a theocratic state.
The entire system of American government is set up to avoid extremes and ensure that any change which occurs is glacially slow. We also have an entrenched system of corporate and political interests that have accumulated a great deal of power and wealth from the current system, and I find it highly doubtful that they would allow an extreme government to come in which leaned to the left or to the right.
If anything, I our government continuing to become more like China's: a corporate friendly authoritarian security state which generally leaves its citizens alone, as long as they shut up and don't trouble.
