Which state's rurals offer the Republicans the most room for growth?

Rural black areas in the south, from depopulation but also from votes flipping in my opinion. If racial tensions ever take a back seat, there’s literally no other reason for them to be voting blue. I could see it following the same trajectory as the middle south, rural Midwest, and rural Texas. All of these were thought to be insulated from geographic polarization

New Mexico also... however the population is so urbanized that it might be hard to notice this trend from a higher level.
