The other night I saw a guy on TV who said he was voting for Trump and the republicans because Hillary and the democrats were against coal and he thought Trump would get him his coal mining job back. Unfortunately for him no one can get his coal mining job back.
Coal mining jobs are lost for two reasons and they have nothing to do with anything Obama or the democrats did. The main reason is coal is more and more mined by machine needing fewer and fewer workers. Second, fracking has made domestic oil and gas plentiful and cheap. I think we now import less oil and even export some. And if it wasn't against the law we would export natural gas.
If coal miners want to vote there best interest they should vote democratic because the democrats will help them train for a new job, the republicans will just let capitalism take its course. Now there is nothing wrong with capitalism, but sometimes people need a little help.
