TN-6 · House

The district, in brief

Tennessee's 6th encompasses the eastern portions and suburbs of Nashville, including Hendersonville, Gallatin and the eastern part of Lebanon, and extends across northern Middle Tennessee and the Cumberland Plateau, taking in Cookeville and Crossville and reaching Scott County. 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 seat is open: Republican incumbent John Rose, re-elected with 68.0% of the vote in 2024, is retiring to run for governor. The Republican nominee is Johnny Garrett, state representative from the 45th district since 2019, who won a four-way primary with 43.6% over Van Hilleary (29.7%), Rose's chief of staff and a former U.S. representative who had raised $1,502,905, Jon Henry (19.6%) and Natisha Brooks (7.0%). The Democratic nominee is Mike Croley, a former park ranger, who won a five-way primary with 28.9% over Chaney Mosley (24.0%) and the 2024 nominee Lore Bergman (23.0%). Independents Chris Monday and Angus Purdy have declared.

As of June 30, 2026 Garrett had raised $2,314,281 with $780,433 on hand; as of March 31, 2026 Croley had raised $14,730 with $6,328 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).

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 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.; The text does not say why Megan Barry was not on the ballot.

Who holds the seat now

John W. Rose (Republican), in this chamber since 2019, 4 terms. Committees: House Committee on Agriculture; House Committee on Financial Services.

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 3.0 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 538,843 adults 25 and over. In 2020 the district voted 39.8% Democratic (two-party) for president. With the same preferences and a 2022-style midterm turnout, it would vote 40.3% Democratic: the midterm electorate alone moves the margin 1.0 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 August 19, 2026; $754,842 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 -32.2 to -1.5 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+28.2): 14.7 pts toward the Republican; 2024 House lean: 3.0 pts toward the Republican; religion: orthodox (0.9%): 1.4 pts toward the Democrat; asian share (1.7%): 0.6 pts toward the Republican; foreign born share (6.2%): 0.5 pts toward the Democrat.

How sure is it, and of what?

Total sd 9.29 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).
