Lake County, home to Leadville at nearly 10,200 feet, carries a union-inflected political tradition from its hard-rock mining past. Its roughly 7,800 residents returned a double-digit Democratic margin in 2024, bucking the rural Colorado trend.
The Democratic margin in Lake County reached its widest at ninety-two points in 1896. The margin in 2024 was sixteen points — still decisive.
Lake County's loyalty is rooted in its place. Median household income of $96,575, a 64% non-Hispanic-white share, and a population of 7,380 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Clatsop County and Presidio County.
