In Tuesday’s big vote, politics matter.

So, too, does religion.

On Election Night, here are five revealing questions that Godbeat pros will be asking:

1. Was President Donald Trump able to maintain his overwhelming level of support — roughly 80% in 2016 — among White evangelicals?

“If that number is significantly lower, I would think it has to do with younger evangelicals and maybe women evangelicals getting fed up,” said Kimberly Winston, an award-winning religion reporter based in California.

The pre-election outlook? Trump is “losing ground with some — but not all — White Christians,” reports FiveThirtyEight’s Amelia Thomson-DeVeaux.

On the flip side, Christianity Today’s Kate Shellnutt highlights evangelical voters who express “more faith in Trump” than they did four years ago.

2. What difference did Catholic voters make, particularly in all-important swing states?

NPR religion correspondent Tom Gjelten notes that in 2016 “it was not the evangelicals who carried Trump to victory but Catholics, a group he had rarely mentioned in his speeches.”

Gjelten explains:

Despite losing the popular vote, Trump reached the presidency in large part because he won traditionally Democratic Pennsylvania, Michigan and Wisconsin, all states in which Catholics outnumber evangelicals by significant margins.

Religion Unplugged’s Clemente Lisi, The Atlantic’s Emma Green and the Columbus Dispatch’s Danae King offer more insight on this key voting bloc. This is has also been a major topic in GetReligion coverage of American politics for more than a decade, especially in the work of Richard Ostling and Terry Mattingly.

3. How did various subgroups — Mormons, Muslims and even the Amish among them — influence the outcome?

Trump’s campaign has made a “concerted effort” to expand support among Arizona and Nevada members of the Church of Jesus Christ of Latter-day Saints, the Salt Lake Tribune’s Lee Davidson reports.
