Perception is not reality. I know many people who are more obsessed with how they are perceived than with actually being the person they are claiming to be. The political world is no different. Many of today's evangelical Republicans desire the perception of wanting a "Christian nation," but without any intention of ever creating a truly Christian nation.
A genuinely Christian America would be forced to do some things that most evangelicals will never be on board with. Following the teachings of Christ would make certain demands upon our society that these evangelicals would vehemently fight against.
