The district, in brief

Tennessee's 3rd encompasses most of the Chattanooga metro in eastern Tennessee, along with suburban and rural areas near Knoxville and the Tri-Cities. The facts record the lines as a map first used in 2026; the text does not discuss the redraw or give a presidential result on the new lines.

The incumbent is Republican Chuck Fleischmann, re-elected with 67.5% of the vote in 2024 and unopposed in his primary with 76,463 votes. The Democratic nominee is Anna Golladay, a small business owner, who won her primary with 79.6% over Bryan Martin (20.4%). Five independents have declared: Dean Arnold, Jean Howard-Hill, Rodney Joe King, Donnie Lynn Ownby and Edward John Roland.

As of June 30, 2026 Fleischmann had raised $2,319,124 with $4,838,423 on hand; as of July 17 2026 Golladay had raised $55,554.79 with $33,870.46 on hand. Every rater listed calls the seat R: Decision Desk HQ (July 14, 2026), the Cook Political Report (February 6, 2025), Inside Elections (March 7, 2025) and Sabato's Crystal Ball (August 14, 2025).

Not in the source: The text does not describe how the 2026 map changed the district.; No presidential result is given on the new lines; the facts' baseline is on the 2024 map.; No general-election polls are recorded, and the model's basis says no district polls.; Ratings are only given as 'R' with no gradation, and no endorsements are listed.

Who holds the seat now

Charles J. "Chuck" Fleischmann (Republican), in this chamber since 2011, 8 terms. Committees: House Committee on Science, Space, and Technology; 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

Two-party margin201620202024
PresidentR+36.9R+32.3R+36.2

A shift of 0.7 points toward the Democrats 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 544,907 adults 25 and over. In 2020 the district voted 33.9% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 33.7% Democratic: the midterm electorate alone moves the margin 0.2 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, 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.

The 90% interval runs from -41.3 to -11.6 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+34.7): 18.2 pts toward the Republican; 2024 House lean: 4.6 pts toward the Republican; experience gap (-4 levels, D minus R): 0.8 pts toward the Republican; asian share (1.4%): 0.7 pts toward the Republican; religion: evangelical (44.7%): 0.5 pts toward the Democrat.

How sure is it, and of what?

Total sd 9.08 points, made of the seat's own volatility 91%, correlated polling error 9%. 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 0b33151b-a949-47f1-b845-564833a2b74d, 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).
