It was one of those symbolic questions that pollsters toss into the mix when probing fault lines inside political coalitions.

The Pew Research Center recently asked, as part of its "Beyond Red vs. Blue" political typology project, whether voters agreed or disagreed that it is "necessary to believe in God to be moral."

Among the voters called "Solid Liberals," one of three major Democratic Party camps, only 11 percent of those polled said "yes." People in the emerging "Next Generation Left" felt the same way, with only 7 percent affirming that statement.

However, things were radically different among the voters that Pew researchers labeled the "Faith and Family Left." In this crowd -- the survey's most racially and ethnically diverse camp -- an stunning 91 percent of those polled saw a connection between morality and belief in God.

"That number, the size of that gap, jumped out at me" in the results, said Carroll Doherty, director of political research at the Pew Research Center.

Faith and Family Left voters are "pretty loyal Democrats, the kind that supported Bill Clinton and Al Gore. They voted for Barack Obama in 2008 and most of them voted for him again in 2012," he added. "But when it comes to moral and cultural and religious issues, they take a very different approach" from the Solid Liberals and those in the Next Generation Left.
