If yiu're going to be in the Ft. Worth area, look into areas around Azle, as you suggest. In adjoining counties, stay away from Decatur in Wise County since it's trending toward the illegal types. Parker County isn't too bad but Weatherford also has a big illegal element. I've found this map to a good guide to avoid leftist regions.
Thanks so much. I was able to track down the article that featured the graph you posted. Aside from hurricanes, Brazoria County is appealing, where Ted Cruz serves. I will definitely research the Azle area. A deputy sheriff I know says to avoid Springtown, too, in Parker County.
