She COULD have rolled it into a victory like this:
"I'm going to tell you something right now that not a lot of people know... my great grandfather was a coal miner in Durham, England. Moved to Scranton with his six kids dreaming of a better life for all of them. I'd like to see a better life for your fathers, brothers, and sons that doesn't involve risking their lives underground for a few scraps of coal that they'll never share in the profits on."
Serious question, which state she alienated and how?
Pennsylvania. She gave a speech in neighboring Ohio where she said:
“We’re going to put a lot of coal miners and coal companies out of business.”
That echoed through coal country, and while nobody expected her to win states like West Virginia, it absolutely killed her in PA.

Instead? "Imma put a bunch of you out of work. U mad bro? LOL."
Hilary Clinton is the definition of hubris.
