Anchored in the Central Valley's agricultural heartland, this district delivered a 27.8-point Republican margin in 2024 — a stark contrast to the statewide pattern and a reliable benchmark for tracking rural conservative turnout in California.

A population of 1,024,074, a 31% non-Hispanic-white share, and a median household income of $107,782 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 30 and State Senate District 22.
