A Republican is concerned about the intersection of religion and politics? That's.....interesting.
Any objective analysis would conclude that the Democrats are far more into using religion to prop up their policies -- from Obama claiming that Jesus would support his budget to Nancy Pelosi claiming that her job as Speaker was to implement policies that comport with the Gospels to the ubiquitous Democrats braying about "What Would Jesus Cut?". Oh, and Congressional Democrats demanding more support from churches for their policies.
I'd say the democrats do use religion in politics a good amount, but "far more" is just preposterous when you consider the fact that in states where the conservative ratio is out of wack (my state), the only thing a republican needs to run on are their christian values it seems like. Plus the fact that it was the Moral Majority and the Christian Right that energized the Republican party and moved them towards social conservatism.
