They usually don't. They go to church and own bibles and all because that's what "good" people do. But by and large they don't think there's an invisible, omnipotent being controlling everything. If there was why would you have to pull yourself up by your bootstraps? And why would a grand cabal of Democrats be able to control everything?

There's exceptions but I really doubt a very large portion actually believe. It's why they get so upset over alternative behaviors. Someone isn't following the "rules" so they should be punished.
