Clinton argued rather unartfully that miners were going to lose jobs. Coal is a diminishing resource. It is not being used like it was. That shrinks everything, jobs, mines, and salaries.

Who wants to face it that soon their lives will be in upheaval.
Trump simply lied saying what he knew they wanted to hear.l Trump played them like he plays everyone.
