Look at the electoral map. Republican dominated areas tend to be rural which is the environment least well suited to EV use.
Democrats tend to live in urban hives and the urban rim, where trips are short, power is generally steady (not subject to long outages like rural areas), and charging stations have been constructed.
The base problem isn't political, it's geographic, which brings with it issues of range, ability to charge, load capacity, reliability in times of crisis, in a physical environment that is unforgiving in inclement weather, or just by virtue of climate.
All physics and economics aside, one size does not fit all, and EVs are less suitable for rural applications than ICE powered vehicles as a rule.
