U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
CA-46 anchors around Santa Ana and parts of Orange County, a region transformed by decades of Latino population growth. In 2024 the district returned an 16.1-point Democratic presidential margin, reflecting one of the sharper leftward shifts in Southern California's historically competitive county.
Across the recorded series it reached a Democratic high of 46.2 points in 1912 and a Republican high of 43.9 points in 1924. Between 2020 and 2024 the district moved 12.1 points toward the Republican candidate; the 2024 margin was 16.1 points.
A population of 759,104, a 18% non-Hispanic-white share, and a median household income of $93,299 describe the district. The district's voting pattern over the last decade is most similar to that of Congressional District 31 and Congressional District 52.
The congressional districts whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
