Norris, TN

[TransfemmeGoreVidal]

Not sure if this fully answers your question, but on wiki it says "Today Norris primarily serves as a bedroom community for Knoxville and Oak Ridge". It also seems particularly beautiful and has a slightly higher median income than neighboring communities, so perhaps it's one of those ruralish liberal enclaves.

I could also see some residual pockets of ancestral Democrats with a fond memory there of the TVA. Maybe there is some relevance there.
