A recent Pew Research Center study on the United States and religion shows a downward trend of Americans who believe in God and pray daily. Specifically the religiously “unaffiliated” population of Americans has increased from 16.1 percent in 2007 to 22.8 percent.
Inside the data, however, there’s another trend that is more subtle but definitely striking: the largest religious group that makes up the democratic party is “unaffiliated.” To quote the Pew study: “Religious “nones” are now more numerous among Democrats and Democratic-leaning adults than are Catholics, evangelical Protestants, mainline Protestants or members of the historically black Protestant tradition.”
For contrast, unaffiliates in the GOP have also grown since 2007, but from 10 percent to 14 percent.
