Any specific thoughts on nice places to begin looking?...since you have actually been to most of these places, it seems.
I used to live in Asheville. It wasn't for me.
There is North Georgia--all the areas where "Deliverance" was filmed, the Chatooga River, Rabun County, Clayton, Haiwasee. The Fontana Lakes/ Tennessee River areas in Tennessee/NC have not been completely developed. I don't know much about rural Mountainous Alabama--except discovering that the pine flatland actually ends in hills around Huntsville. Banner Elk, Boone, Blowing Rock NC--The New River Valley in WV. There is a lot to look at.
You're not going to find a perfect political situation, either--but you won't have to live in a population of liberals.
And if you really want the bucolic isolated Rivendell--you're going to have to learn to cook to please yourself.
