Third column names the leading third-party or independent finisher. Source · MIT Election Lab · ICPSR · VEST (precinct-level 2024). Swing · margin change from the prior cycle. vs U.S. · margin relative to the national result that year. Third-party votes in 2012 are allocated from certified county totals by this place's share of each county's two-party vote — that cycle's precinct source records two-party splits. † 2004 sub-county results are estimated: the source's block-level detail for this cycle was unreliable — either county/municipality-level consolidated reporting (COVID-era) or a precinct-to-block allocation that misplaced votes — so the figures are allocated from the constituent county totals in proportion to the place and scaled to certified totals.

With a 2024 presidential margin of D+24.7, this district ranks among the state's most reliably left-leaning constituencies, suggesting a dense urban or majority-minority population base that consistently drives lopsided down-ballot results.
Across the recorded series it reached a Republican high of 28.1 points in 2004. Between 2020 and 2024 the district moved 1.4 points toward the Republican candidate; the 2024 margin was 22.1 points.
A population of 217,984, a 63% non-Hispanic-white share, and a median household income of $76,408 describe the district. The district's voting pattern over the last decade is most similar to that of State Senate District 32 and State Senate District 29.
