NY-8 · House
election-day forecast · ground-up model · as of 2026-10-02
The district, in brief
New York's 8th is based in Southern and Eastern Brooklyn, including Bed-Stuy, Brownsville, East New York, Canarsie, Bergen Beach, Sheepshead Bay, Gravesend and Coney Island. The lines are the map first used in 2024 and the district was not redrawn for this cycle. The facts record a 2024 presidential two-party margin of 44.7 for the Democrat on the current lines.
The incumbent is Democrat Hakeem Jeffries, the House Minority Leader, who has represented the district since 2013 and was re-elected with 75.4% of the vote in 2024. Councilmember Chi Ossé, a DSA member, sought to challenge him from the left, but on November 22, 2025 the New York City DSA voted against endorsing him, after lobbying by Mayor Zohran Mamdani and Alexandria Ocasio-Cortez, and Ossé ended his campaign two weeks later. The one primary poll, Z to A Research (D) of September 15–30, 2025, had Jeffries 72% and Ossé 21%. The Republican nominee is Lewis Mizrahi, a data analyst, who also runs on the Conservative line. As of June 30, 2026 Jeffries had raised $14,899,981 with $5,000,460 on hand; Mizrahi reported $0.
Every rater listed calls the seat D: Decision Desk HQ (July 14, 2026), the Cook Political Report (February 6, 2025), Inside Elections (March 7, 2025) and Sabato's Crystal Ball (September 18, 2025). The text records no general-election polls.

Who holds the seat now
Hakeem S. Jeffries (Democrat), in this chamber since 2013, 7 terms. No committee listed.
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
| Two-party margin | 2016 | 2020 | 2024 |
|---|---|---|---|
| President | D+63.9 | D+55.2 | D+42.8 |
A shift of 21.1 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?
| Group (adults 25+) | Share of adults | Turnout 2020 / midterm | Share of a midterm electorate | Est. Democratic share, 2020 |
|---|---|---|---|---|
| White, no degree | 13% | 57% / 43% | 14% | 25% |
| White, degree | 17% | 77% / 67% | 29% | 76% |
| Black | 44% | 57% / 36% | 40% | 95% |
| Hispanic | 14% | 38% / 26% | 9% | 80% |
| Asian | 8% | 34% / 22% | 5% | 71% |
| Other / multiracial | 3% | 57% / 44% | 3% | 74% |
Of about 550,460 adults 25 and over. In 2020 the district voted 77.8% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 76.5% Democratic: the midterm electorate alone moves the margin 2.6 points toward Republicans. 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.

ACS 5-year 2023, the Census Bureau's own tabulation of this district (118th Congress lines). 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 +41.9 to +69.7 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+46.2): 41.2 pts toward the Democrat; 2024 House lean (D+53.5): 15.1 pts toward the Democrat; experience gap (+4 levels, D minus R): 12.6 pts toward the Democrat; PAC money balance: 9.5 pts toward the Democrat; 2020 presidential lean (D+51.2): 2.7 pts toward the Democrat.
How sure is it, and of what?
Total sd 8.43 points, made of the seat's own volatility 90%, correlated polling error 10%. 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).
