Hey, news consumers: Does anyone remember that "Nones on the Rise" study from the Pew Research Center?

Of course you do. It was in all the newspapers, over and over. It even soaked into network and cable television news -- where stories about religion is rare.

The big news, of course, was the rapid rise in "Nones" -- the "religiously unaffiliated" -- in the American population, especially among the young. Does this sound familiar? One-fifth of all Americans -- a third of those under 30 -- are "Nones," to one degree or another.

Traditional forms of religious faith were holding their own, while lots of vaguely religious people in the mushy middle were being more candid about their lack of ties to organized religion. More than 70 percent of "Nones" called themselves "nothing in particular," as opposed to being either atheists or agnostics.

When the study came out, a key researcher -- John C. Green of the University of Akron -- said it was crucial to note the issues that united these semi-believers, as well as atheists, agnostics and faithful religious liberals, into a growing voter block on the cultural left. My "On Religion" column ended with this:

The unaffiliated overwhelmingly reject ancient doctrines on sexuality with 73 percent backing same-sex marriage and 72 percent saying abortion should be legal in all, or most, cases. Thus, the "Nones" skew heavily Democratic as voters. ... The unaffiliated are now a stronger presence in the Democratic Party than African-American Protestants, white mainline Protestants or white Catholics.

"It may very well be that in the future the unaffiliated vote will be as important to the Democrats as the traditionally religious are to the Republican Party,” said Green. ... "If these trends continue, we are likely to see even sharper divisions between the political parties."

These sharp divisions are also being seen INSIDE the major political parties. If you want to see that process at work, check out the fascinating New York Times report that ran the other day under this headline: "As Primaries Begin, Divided Voters Weigh What It Means to Be a Democrat." It isn't hard to spot the religion "ghost" in this blunt overture:

PALOS HILLS, Ill. -- When Representative Daniel Lipinski, a conservative-leaning Democrat and scion of Chicago’s political machine, agreed to one joint appearance last month with his liberal primary challenger, the divide in the Democratic Party was evident in the audience that showed up.
