No doubt about it, most mainstream pollsters thought the vote totals that rolled in during Election Night 2016 were intriguing, then stunning and, as dawn approached, almost unimaginable.

How did the chattering-class insiders miss what was clearly widespread heartland support for New York billionaire Donald Trump?

But there was one surprise left in the details of the early exit polls. In a race packed with soap-opera conflict and fiery rhetoric about personal ethics, morality and even faith, the experts looked at the role that religion played in 2016 and discovered -- to their shock -- that it was a rather normal modern election year.

"Actually, that's astonishing news," said Gregory A. Smith, who helps coordinate religion polling at the Pew Research Center. "If you consider all of the tumultuous events during this election year and how much tension there has been and all of the other stuff that's been up in the air, it's amazing that things were so steady" in terms of religion and voting, with "only a few numbers up or down a bit.

"Religious groups that have consistently supported the Republicans gave every indication they would back Donald Trump and that's how things turned out. The religious groups that traditionally back Democrats did so, but the turnout was down a bit. The religious groups that are usually divided were divided."

The so-called "God gap" (also known as the "pew gap") held steady, with religious believers who claimed weekly worship attendance backing Trump over Hillary Clinton, 56 percent to 40 percent. Voters who said they never attend religious services backed Clinton by a 31-point margin, 62 percent to 31 percent.
