Is there any state where the religious nones vote GOP?

[King of Kensington]

Maybe Alaska or Wyoming?

Definitely these two, and probably at least the Dakotas as well.

Wyoming and Idaho most likely, those two states are part of what is called the "Unchurched Belt" in the Northwestern United States. I think there might have been a decent swing toward the GOP among religious nones in Maine and New Hampshire in 2016 as well, though not enough for the GOP to win that demographic.

I recall reading that Idaho, Wyoming, and Alaska had more religious nones than followers of any one particular Christian denomination according to data from the 2000s or early 2000s, so they would probably be the best candidates.

However, it’s important to consider turnout disparities, the American Indian/Alaska Native populations, as well as the fact that 30-40% of the population (the proportion of people from those states who vote Democrat) is still a very large and statistically significant group of people.

[I’m not Stu]

No. They might be more GOP than in most states, but they still likely vote Democratic overall. Wyoming and Idaho have a fairly large Mormon population. Catholics are also common. Alaska is far less GOP than Wyoming and Idaho. Is overall turnout good in those states?

It's worth remembering that "no religion" or "no affiliation" is not akin to "atheist" or "agnostic."

Many of those people are very "culturally Christian" and hold socially traditionalist views on sex/gender.

White religious nones in the south are going to be voting GOP and are going to be the voters that swung the greatest to Trump.

Why would religious nones there vote Trump?

Maybe, but the Dakotas are among the most religious states.

Which Christian denominations are prominent in the Dakotas? Religious nones in South Dakota voted for Billie Sutton by a landslide margin.

Oh, so they probably aren’t Republican.

Lutherans are the largest denomination, followed by Catholics.  The Dakotas are about as Catholic as the national average, while they are the most Lutheran states.  They may even be the most Mainline Protestant states.

Religious nones in South Dakota are probably heavily Democratic. Catholics are the largest denomination in California, which is the case in many urban states.

I'd be willing to be that most of those people still identify as Christians, even if they don't practice because as you said, they're still culturally Christian. Being a none is still the territory of those who are "spiritual and not religious" and are trying to make a statement against organized religion and the culture around it.

Anyway, to answer the question, I'd guess that there's likely no state where nones vote GOP - looking at presidential and midterm results from the last few cycles, Democrats regularly get high 60s to low 70s results with nones, which likely translates Dems winning them everywhere.

Why are Lutherans the most common in the Dakotas?

[King of Kensington]

Why are Lutherans the most common in the Dakotas?

Because most people in the Dakotas are of German or Scandinavian ancestry.

Is German ancestry the reason Catholics are common in the Dakotas?
