Normally appealing to the local businesses might work, but this is stronger than a few additional customers (who would likely be customers if forced to make the trip in an ICE). A small town like this has some very influential people in control. Very likely, they are big land owners with oil interests.
Take a look at the stretch of I-10 just to the east of Ft. Stockton:

Every one of those little white splotches is an oil drill site -- some with pumps, some not successful. Somebody owns all that land and has lots of money that (in their estimation) will dry up if the electric car is successful. The land certainly isn't good for anything else.
Team that up with car dealers who have been there forever and are the only dealerships for hundreds of miles, and you have lots of money contributing to lots of campaigns and nobody really watches politicians in these areas to see that they are taking influence money.
You won't get the businesses to unite and rise up. Every little piece of government is bought and paid for. They won't get health inspections approved. Their taxes will go up. Their licenses will get revoked.
The only choice is to move outside the city, but the county government is perhaps just as bad. Then there is the issue of no utilities outside the population areas -- they can't just pop a SC at the next gas station -- it's miles away in Ozona (and they already have a SC).
