CA-49 · House

The district, in brief

California's 49th is recorded in the facts as redrawn for 2026, on a map first used this cycle; the text says nothing about the new lines. The incumbent is Democrat Mike Levin, re-elected with 52.2% in 2024.

Levin faces Republican Armen Kurdian, a retired navy captain. In the top-two primary Levin took 55.85% and Kurdian 26.10%, with Republican Star Parker, a columnist and 2010 nominee for the 37th district, eliminated at 18.04%. Republican supervisor Jim Desmond withdrew to run in the 48th district. As of May 13, 2026 Levin had raised $2,893,833 with $1,383,634 on hand; Kurdian $23,196 with $7,417 on hand. The endorsement list that names Senator Adam Schiff, Representatives Sara Jacobs, Scott Peters and Juan Vargas, AIPAC, J Street and the California Democratic Party is not labelled by candidate in the extract; a separate one-line list names Darrell Issa.

Every rater listed calls the seat D: Decision Desk HQ (September 8, 2026), Inside Elections (November 6, 2025), the Cook Political Report (November 5, 2025), Sabato's Crystal Ball (February 5, 2026) and The Economist (May 6, 2026). The text records no general-election polls.

A paragraph quoting a model forecast from the day this brief was written is omitted; the current forecast is at the top of this page.

The facts, each beside its sentence

Not in the source: The facts mark the district as redrawn for 2026, but the text does not describe the new lines or give presidential results on them.; No district polls in the text; the model's basis also says no district polls.; Candidate headings over the endorsement lists were lost in extraction, so the text does not say whom Schiff, Jacobs, Peters, Vargas or Issa endorsed.; No general-election ratings finer than 'D' are given (no Lean/Likely/Safe).

Who holds the seat now

Mike Levin (Democrat), in this chamber since 2019, 4 terms. Committees: House Committee on Appropriations.

From the congress-legislators dataset (CC0), archived as ae8cb9477c48. For a Senate race this lists both of the state's senators; the one whose term ends in the election year holds the seat on the ballot. For a House district redrawn for 2026 it is the member elected under the old lines with this number, who may be running elsewhere; the dossier above names who is running here.

How it has voted for president

A shift of 4.4 points toward the Republicans from 2016 to 2024. county returns placed on the current lines by 2020 block population; MEDSL county file (2016), an MIT-licensed county file (2020, checked against certified state results) and MEDSL precinct returns (2024). For a district split across counties this is an estimate, and where the state published the exact 2024 figure for these lines, that exact figure is the one the model uses.

Who are the voters?

Of about 497,725 adults 25 and over. In 2020 the district voted 57.8% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 58.5% Democratic: the midterm electorate alone moves the margin 1.4 points toward Democrats. Group shares are estimated from how results vary across the state's census tracts (ecological inference, anchored to Pew's 2020 validated-voter figures) and calibrated to this district's actual 2020 vote; turnout is the Census survey's state rate by race and national rate by education, whose state samples carry margins of several points.

Not answered here: how each group will vote in 2026. These are 2020 preferences; this profile is description, not yet an input to the forecast.

The money

FEC bulk candidate summaries through June 30, 2026; $7,746 of independent expenditures for or against these candidates this cycle (FEC Schedule E, types 24E and 24A), which is the parties' and outside groups' own revealed view of whether this seat is in play.

The district in numbers

ACS 5-year 2023, assembled from census tracts by the 2020 population of their blocks inside the current lines, because the Bureau has not tabulated these lines; medians are population-weighted means of tract medians. Unemployment is the BLS county series placed on the district by block population, not seasonally adjusted, so changes are same-month comparisons. Income, transfers and jobs are BEA county accounts placed the same way, compared with the average district. Every other figure is a named column of a named table in the Bureau's summary file, archived before it was read. This is what a reader knows about a district before looking at a poll; the model does not yet use it, and whether it should is a registered question.

Who is favoured, and by how much?

The 90% interval runs from +8.8 to +38.7 points, D-R. It is wide because this district has never been polled.

What is this built on?

A model trained on every contested House race 2012-2024 predicts this district's lean from its own record: presidential and House results on the current lines, incumbency, both candidates' prior offices, outside and party money before 1 October, demographics and public-assistance shares from the Census release before the election, local unemployment and income, and religious tradition. The national margin comes from presidential approval, the economy, the midterm penalty and the generic ballot corrected for its measured lean. Draws share national and state errors, so the seat total and this district come from the same simulation.

Not answered here: district polls, which are not yet folded in.

Why does the model say this?

Each figure is how far this district's predicted lean moves when that one feature is set to the typical value across 2026 districts, everything else held: 2024 presidential lean (D+14.0): 10.1 pts toward the Democrat; 2024 House lean: 7.9 pts toward the Democrat; PAC money balance: 7.8 pts toward the Democrat; experience gap (+4 levels, D minus R): 2.1 pts toward the Democrat; total outside/party money: 1.2 pts toward the Democrat.

How sure is it, and of what?

Total sd 9.10 points, made of the seat's own volatility 92%, correlated polling error 8%. The decomposition is stored with the forecast rather than reconstructed, so a probability whose dominant input is a placeholder is visibly that.

Not answered here: a nowcast. 'If ballots were cast today' needs something that observes today, and for a House district nothing does. Publishing the election-day figure under both labels would make one forecast look like two.

How was this number made?

Run 6f211e6f-2bdc-4dda-8f72-81fc628dab0b, house_district_prior/0.2.0, as of 2026-10-02. Promoted by a pre-registered gate: on 2016-2022 its Brier score was 0.036 against 0.049 for the previous method, and on a single 2024 run 0.023 against 0.032 (experiments/district_gate_result.md, with an independent review).
