Is it possible that West Virginia remained a low-income state because it followed to policies of the Democratci party for close to 70 years?
West Virginia is a state full of natural resources that are owned and exploited by liberal blue state industrialists. The last thing these blue staters want is a self sufficient Appalachian. It worked for quite consistently from the Great Depression until 1980.
Does the name Rockefeller ring a bell?
Note, West Virginians still elected the usual Democrat congressional suspects: J.D. Rockefeller IV in 2000, and the idiot representatives Mollohan and Rahall. That Shelley Moore Capito was elected to Congress is a major accomplishment. Another Republican in the House or Senate would be earthshaking.
