King County's presidential margins have widened steadily since 2000 as the Seattle metro absorbed waves of highly educated in-migrants, while Pierce County to the south continues to post noticeably closer results, anchoring competitive state legislative districts.
Across the recorded series it reached a Democratic high of 36.9 points in 1936 and a Republican high of 52.5 points in 1904. Between 2020 and 2024 the market moved 0.7 points toward the Republican candidate; the 2024 margin was 28.5 points.
A population of 5,596,124, a 61% non-Hispanic-white share, and a median household income of $108,368 describe the market. The market's voting pattern over the last decade is most similar to that of Portland, OR and San Francisco-Oakland-San Jose.

Political twins — media markets
The media markets 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.
