If anything, revealing that President Clinton was far more overtly religious than President Bush is an interesting demonstration about how religiosity is reflected in our culture and among our politicians. Especially because we’ve seen a lot of propaganda attempting to reflect poorly on President Obama by claiming he’s a Muslim, and then shortly (almost in the same breath) blaming him for the wacko-crazy Christian church that he belonged to.
Politicians pander to people in the ways they believe they’ll respond to; religion is both a great divider and a powerful motivator.
Of course, we’re probably not going to see any sort of religious vs. non-religious schism in political frames since really most of the class and language warfare is reflected between the empowered groups and disenfranchised groups. It’s about groping around and holding onto power in the face of other groups trying to take it away — or, especially in the case of the Information Age, the Internet bleeding power away from concentrated groups who maintain themselves by attempting to indoctrinate their children (or citizens, or parishioners) by lensing them a false vision of the rest of the world.
