2032 redistricting
Flagged as a 2032 redistricting risk.California’s Citizens Redistricting Commission draws the map after each census: 14 members, 5 Democrats, 5 Republicans and 4 from neither party. For the 2026, 2028 and 2030 elections the state uses a map the Legislature passed in August 2025, which voters approved as Proposition 50 on November 4, 2025. The commission draws again in 2031. Cal. Const. Art. XXI, Sec. 2 (opens in a new tab); Cal. Const. Art. XXI, Sec. 4 (opens in a new tab).

Lean is the Cook Partisan Voting Index (PVI) on the district’s 2026 election lines: R+10 and up is solidly Republican, R+5 to R+9 lean Republican, D+4 to R+4 swing, D+5 to D+9 lean Democratic and D+10 and up solidly Democratic. A 2032 redistricting flag marks one of seven states American Ascent watches for the maps drawn after the 2030 census, with who draws the map there.

What a race here costs

Facts from free public data: the TV markets the district sits in, what every campaign and outside group spent in recent races, and the votes cast. Spending is campaign spending, less contributions to party committees and other candidates, plus independent expenditures. A vote is any vote cast in that contest.16

TV markets

The TV markets that cover the district
MarketTV homesOf the districtDistrict is, of market
Sacramento–Stockton–Modesto, CA (rank 20)1,497,920100%16.3%

Markets are Nielsen’s Designated Market Areas, matched to the district county by county on the 2026 lines (3 counties or parts). Shares are of people, from the 2020 Census. TV homes are Nielsen’s 2024-25 estimates. A small share of a large market means most of what a TV buy reaches lives outside the district.11
