Gawd forbid we have a POTUS candidate stating a desire to move us forward from coal production to sources of cleaner renewable energy. What a bitch! Perhaps you never heard the news that some of these efforts to transition coal miners to other jobs included an offer for FREE training to prepare them to move into the 21st century?

From the article you quoted:  
.
In her new book, "What Happened" — officially out next Tuesday — Hillary Clinton wrote that her biggest regret from the campaign trail last year was saying she would put coal miners out of business. CNN, which obtained a copy of the book this week, reported that the 2016 Democratic presidential nominee said that comment was the one "I regret the most."
Clinton made the remark during a town hall in Columbus, Ohio, in March 2016 when she touted her plan to replace fossil-fuel-based energy production with renewable systems.
.
"I'm the only candidate which has a policy about how to bring economic opportunity using clean renewable energy as the key into coal country," she said. "Because we're going to put a lot of coal miners and coal companies out of business."
.
She quickly added that she wanted to help coal miners and other workers who gave their health and sometimes their lives to produce the nation's energy.
