Dan Kahan (who is not to be confused with Daniel Kahneman, but good luck with that) has once again put some interesting data up on his blog at the Cultural Cognition project.
At the dailykos we often ask ourselves just what our esteemed friends on the right are actually thinking. "The Cultural Cognition Project" is about trying to answer questions like that rigorously instead of just with handwaving.
At the core of the current post is some graphs of survey results that try to separate the effects of religious attitudes and political affiliation.
In summary: it appears that on climate change, "religiosity" has only a small effect, but on evolution or stem-cell research it has a big effect. And on nuclear power, "religiosity" doesn't seem to make any difference.
I recommend taking a look at his graphs, but just skim the surrounding text until the graphs start to make sense. His writing skills are a little weak, and I usually find his attempts at being clever more confusing than amusing.
Kahan links to a Chris Mooney write-up at the wapo wonkblog that's pretty good, in comparison.
