Riverside County's rapid population growth — driven by inland migration from coastal metros — has gradually compressed its Republican presidential margins, producing an R+1.3 result in 2024 after double-digit GOP leads just a decade earlier.

The county's recent history is a story of close margins. The Democratic margin reached twenty-nine points in 1912; the Republican margin reached fifty-seven points in 1928. Most other elections have been decided by single-digit points.

Riverside County's demographics — a population of 2,478,600, a 38% non-Hispanic-white share, a median household income of $93,074 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Oktibbeha County and Montgomery County.
