It's real, it's happening...

One-fifth of U.S. adults say they are not part of a traditional religious denomination, new data from the Pew Research Center show, evidence of an unprecedented reshuffling of Americans’ spiritual identities that is shaking up fields from charity to politics.

But despite their nickname, the “nones” are far from godless. Many pray, believe in God and have regular spiritual routines. Their numbers have increased dramatically over the past two decades, according to the study released Tuesday. About 19.6 percent of Americans say they are “nothing in particular,” agnostic or atheist, up from about 8 percent in 1990.

In away, the GOP is right to worry about Obama and his social agenda. Things like universal healthcare will make more Americans existentially secure. And the more existential security there is in America, the weaker American Christianity becomes. And a decline in the number of American Christians will hurt the GOP. The graph says it all.
