Moscow, Idaho. There's a church there that makes up about 10% of the population and wants to make it a "Christian town" according to their leader Douglas Wilson (who recently went on Tucker Carlson's show).
And yet is one of the most Democratic places in the state. Not really a good example.
My grandparents live in the general area around Moscow and have not been happy about the cult trying to take over the town. It's a relatively liberal college town too.
I've jokingly called Northern Idaho a reservation for radical white conservatives. Stuff like this is why.
