The district, in brief

New York's 11th district includes all of Staten Island as well as the Brooklyn neighborhoods of Bay Ridge, Fort Hamilton, Dyker Heights, Bath Beach and Bensonhurst, on the map first used in 2024. The lines are under litigation: a state trial-court judge declared them unconstitutional, the intermediate appeals court upheld that ruling in February 2026, and on March 2, 2026 the U.S. Supreme Court issued a stay blocking the lower court ruling pending further litigation. The text gives no presidential results; the facts record a 2024 presidential baseline on these lines of -24.8 points (two-party margin for the Democrat) and a two-party House margin of -28.2 for the Democrat in 2024.

The incumbent is Republican Nicole Malliotakis, re-elected with 64.1% of the vote in 2024, who also runs on the Conservative Party line and is the only Republican the text lists. Her listed endorsements include Donald Trump and the Staten Island Republican Party. The Democratic nominee is Michael DeCillis, a retired police officer who ran for the seat in 2018 and 2022, who won the primary with 61.4% (10,455 votes) over Allison Ziogas, who had withdrawn but remained on the ballot and took 37.1%. As of June 30, 2026 Malliotakis had raised $2,750,505 with $2,767,340 on hand; DeCillis had raised $67,616 with $35,290 on hand.

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) each list the seat as R. The text records no district polls.

Not in the source: The text does not say what the court challenge to the district lines is about or what a redrawn district would look like; the facts record the lines as not redrawn for 2026.; The text gives no presidential results for the district; only the facts' presidential baseline is available.; No district polls are in the text, and the model's basis says no district polls.; No Republican primary result is given; the text lists only Malliotakis.; No ratings finer than 'R' are given (no Lean/Likely/Safe); Silver Bulletin is not listed.

Who holds the seat now

Nicole Malliotakis (Republican), in this chamber since 2021, 3 terms. Committees: Joint Economic Committee; House Committee on Ways and Means.

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 margin201620202024
PresidentD+9.4D+6.2R+7.8

A shift of 17.2 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 536,328 adults 25 and over. In 2020 the district voted 46.1% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 46.0% Democratic: the midterm electorate alone moves the margin 0.3 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.

The 90% interval runs from -31.7 to -3.3 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 (R+23.3): 8.2 pts toward the Republican; 2024 House lean (R+25.5): 2.5 pts toward the Republican; moved from other state share (0.6%): 1.8 pts toward the Republican; religion: orthodox (0.8%): 1.3 pts toward the Democrat; asian share (19.5%): 1.1 pts toward the Democrat.

How sure is it, and of what?

Total sd 8.60 points, made of the seat's own volatility 89%, correlated polling error 11%. 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?
