What if we woke up tomorrow, and 70% of America was athiests? Would the Republicans stop promising to bring religion into politics? or would they turn a complete 180 and start promising to feed Christians to lions if elected?

Personally I'm inclined to think the latter... because it was never about God to begin with. It's about more power and more money, and catering to the Christian majority in this country is just the easiest way to do it... because so many religious people will blindly elect someone who makes hollow claims to push their values.
