Why unemployed West Virginia coal miners support Trump

Here's a good Guardian investigation on the above. Coal mines in the area have closed due to more stringent environmental standards, as well as the shift to fracking. Hence a once thriving coal mining economy has gone bust. These desperate people believe Trump when he says he's going to open the mines again and put them all back to work. But Trump can't deliver on this promise. We really need retraining in the new renewable energy economy.
