Yes, there were many cherry picked and edited statements used against Clinton. That's what the GOP is good at.

No, I didn't buy it. Coal is dying around the world because gas is cheaper and cleaner, among other reasons. And working-class whites have a long history of voting against their own interests. The point is that a more adept politician would never have handed the opposition that kind of ammunition.
