What’s striking about this chart from Gallup’s new survey of support for Obama by religion?

Not the numbers themselves–they’re exactly what you’d expect them to be. It’s the existence of the None/Atheist/Agnostic category. Thanks to the 2008 Trinity ARIS (sorry for the self-promotion, but truth is truth), the Nones now constitute a recognized category in the American religious spectrum. And that’s as it should be. They have a distinctive profile, demographically and ideologically, and they constitute one-sixth of the voting population–way more than Jews or Mormons.

New categories have a way of creating new realities. The None category is making American religion a different place.
