In our recent Social Science Research article, we demonstrate that both religion and politics play strong independent roles in structuring support for and opposition to same sex marriage. The Republicans have not simply been taken over by the fundies, but instead are also directly complicit in supporting homophobia and opposition to civil rights among their more secular constituents. The above graph updates our findings using the 2010 General Social Survey. Notice that among fundies, who believe the bible is the inerrant word of god, support is very low even if you are a strong Democrat–but it’s twice as high as it is among Republican fundies. Among moderates and seculars, the effect of political party is quite dramatic—67% of strong Democrats who think the Bible was inspired by god support same sex marriage, while among Republicans with the same beliefs support is 18%. Among people who think the bible is bunk, 82% of strong democrats support same sex marriage, while only a third of republican non-believers support civil rights. Party matters.
