A Target on His Back Union assassins tried to kill Colorado’s governor.

Colorado Governor James Peabody was a target—literally—during the labor wars that wracked that state in the early 1900s.  Leaders of the Western Federation of Miners saw him as an enemy who was determined to crush the labor movement (basically true).  So they hired Harry Orchard to get Peabody out of the way.

Orchard and at least one compatriot scouted the governor’s mansion, waiting for Peabody to emerge so that they could shotgun him.  An opportunity never presented itself.  So Orchard set bombs in various places, targeting the governor. Those failed. Peabody later retired, safely.
