El Paso has some, but it is not like Austin.
I lived in Western NM for 14 years. There were genuine lefties there. A mine-union town was the education of this old West Texas Farm Boy. I did battle with the surrogates of the Sandanistas there during the 1980’s. Lived in a town were Dem to GOP was 5 to 1.
El Paso is not like that. Military element, old Hispanic families, many good business people. Yes, the border influence is a real negative.
Many families are married across the border. Most of those own property on both sides of the border.
Have read that about 1/3 of Juarez is unoccupied because of the drug violence. Probably true.
