Republican Donald Trump has won West Virginia and its five electoral votes.
The Mountain State was one of the billionaire's biggest supporters in the Republican primary.
He is popular for promising to bring back coal jobs.
Hillary Clinton had largely been largely shunned for making comments perceived as an affront to the industry.
The dynamic has resulted in one of the few states where Republicans didn't shy from the brash businessman and instead looked to ride his coattails.
Many Democrats for congressional and other races scrambled to distance themselves from Clinton and refused to endorse her.
West Virginia has voted for Republican presidential candidates in each of the last four presidential races. It takes 270 electoral votes to win the presidency.
