TX-30 · House

The district, in brief

Texas's 30th is a new district for 2026, anchored in the southern portions of Dallas, including South Dallas and Fair Park, and stretching south through Dallas County suburbs such as Lancaster, Duncanville, DeSoto, Wilmer, Cedar Hill and southern Grand Prairie. The text records Kamala Harris at 72.7% in the district in 2024 and Colin Allred at 75.1% in his losing Senate race against Ted Cruz. The seat is open: the previous incumbent, Democrat Jasmine Crockett, was drawn into the 33rd and is running for U.S. Senate.

The Democratic nominee is Frederick Haynes III, a pastor and former president and CEO of Rainbow/PUSH, who won the primary with 72.6% over Barbara Mallory Caraway (23.1%) and Rodney LaBruce (4.3%). Crockett endorsed him, as did Greg Casar, Maxwell Frost, Pramila Jayapal, the Texas AFL-CIO, Justice Democrats, the Dallas Morning News and the Fort Worth Star-Telegram, with Giffords and J Street added after the primary. The Republican nominee is Everett Jackson, a business owner, who led the primary with 38.0% and won the runoff 57.5% to 42.5% over attorney Sholdon Daniels. An independent, Oxford Nordberg, has filed paperwork. As of April 26, 2026 Haynes III had raised $347,441 with $124,849 on hand; Jackson had raised $16,948 with $2,406 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) all rate the seat D; the Silver Bulletin row (August 20, 2026) shows no rating.

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: No district polls are in the text, and the model's basis says no district polls.; The Silver Bulletin rating cell is empty; only its date is given.; No general-election ratings finer than 'D' are given (no Lean/Likely/Safe).; The text gives no biography for Jackson beyond 'business owner' and no endorsements for him in the general election.

Who holds the seat now

Jasmine Crockett (Democrat), in this chamber since 2023, 2 terms. Committees: House Committee on the Judiciary; House Committee on Oversight and Government Reform; House Select Subcommittee to Investigate the Remaining Questions Surrounding January 6, 2021.

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 2.4 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 480,075 adults 25 and over. In 2020 the district voted 78.5% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 78.2% Democratic: the midterm electorate alone moves the margin 0.6 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.

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 September 30, 2026; $470,000 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 +30.1 to +60.4 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+49.3): 36.7 pts toward the Democrat; 2024 House lean: 10.3 pts toward the Democrat; PAC money balance: 9.3 pts toward the Democrat; 2020 presidential lean (D+52.8): 3.4 pts toward the Democrat; 2022 House lean: 2.1 pts toward the Democrat.

How sure is it, and of what?

Total sd 9.23 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 00a09d4b-7980-4ec5-ada0-077968a87242, 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).
