Source: MIT Election Data and Science Lab, U.S. House V15 / U.S. Senate V8 (CC0), retrieved 2026-10-18; winners matched to member records by seat and term. Results run through the 2024 elections; nothing from 2026 is shown until it is certified. A margin is a fact about one election, never a score of how well a member represents anyone, and PORKER does not rank members by it.
How has California’s 10th district done while Rep. DeSaulnier served?
2023 to 2024 in CA-10: typical household income was about the same after inflation, the share of people below the poverty line was about the same, and the share of workers looking for a job was up 1.4 points.
Each mini chart has its own scale, fitted to its lines (it does not start at zero), so compare the numbers, not the heights. Teal = district, oxblood = state, grey = U.S.
While they served, not because of them. This shows what happened in California’s 10th district during DeSaulnier’s time representing it (2023 to now). It does not say what the member did or caused. It is not a score, and PORKER never ranks members on it.
One set of district lines. CA-10 was redrawn in 2012 and again in 2022 (the survey year the new lines first appear), but every survey year in DeSaulnier’s term so far (2023 and 2024) uses the same lines, so they can be compared. The Census Bureau has no 2020 yearly estimate.

Read this first. These are counts of records Congress.gov lists. Many bills never get a CBO estimate or a report, so a zero is not a mark against a member. We never show this as a score.
