The idea that government will try to force churches to marry people is a boogeyman, and always will be.
There is enough tricks with each party to keep the other honest(honest being relative....very relative....EXTREMELY relative). With todays politics its difficult to believe one party could take that much control. Its important to keep in mind that, by and large, Americans actually support a bi-partisan government. Its one thing that gives me hope in this country is that we are in favor of forcing compromises.
