According to the folks at Gallup, 8 of 10 people in the U.S. say they are Christian, with 4 of 10 attending church regularly, but this by no means equates to "conservative." I have a lot of friends who are good old social activist leftist, progressive Christians, some gay and lesbian, some not, as are some represented here. Some Christian churches have very progressive policies toward social justice issues, and would likely take issues with being characterized as "predomimantly" conservative. It's a big country.
