Monterey County's large Latino population—many tied to the Salinas Valley's $9 billion agriculture industry—anchors a Democratic margin that has held above 25 points in every presidential cycle since 2008.
The Democratic margin in Monterey County reached its widest at forty-six points in 1912. The margin in 2024 was thirty points — still decisive.
Monterey County's loyalty is rooted in its place. Median household income of $97,230, a 36% non-Hispanic-white share, and a population of 437,613 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 Shelby County and Santa Clara County.
