Washington · U.S. House · District 10 · November 3, 2026

What it would take for Chris D. Chung.

Strickland starts 15.9 points ahead on our starting line from recent official results. Campaign work can move about 7,101 net votes toward Chung, a 2.6-point gain. Winning outright would take a 13.3-point national wave on top of that. Here is the plan that makes Chung the one standing if one comes.

Underdog UpdateSeptember 27, 2026. Underdog plan published. Starting line: Strickland +15.9. Chris D. Chung needs 43,308 net votes. Odds 1% today, 3% with the plan.

The number

135,723 votes.

That is half of the 271,445 ballots we expect in this race, plus one. Where Chung stands today, and what is missing:

112,783 Chris D. Chung baseline

156,091 Marilyn Strickland baseline

Starting line: a weighted blend of the official 2022 and 2024 results in this district (House in 2024 and 2022, President, U.S. Senate in 2022). No 2026 polls have been published. 2026 turnout modeled on 2022, the last midterm.

The odds

1% today. A wave changes that.

We ran this race 20,000 times with realistic error on every assumption. Drag the slider to see the odds move as the campaign captures more of what history says is available.

of 20,000 simulated elections

With no plan

How much of what history allows the campaign achieves100%

The plan on this page sits at 100%. Median outcome at this setting: Chung short by 35,958.

Each simulation draws the starting line with an error of 7 points of margin (no 2026 polls, so the starting line comes from history and carries more error) and lets the plan over- or under-deliver by 30 percent. Seeded and reproducible; the method and data are at the bottom of the page.

Three moves

The gap closes three ways.

Change minds. Bring out voters who skip midterms. Win back the third-party vote. Every pool below is counted from official precinct returns and published polls.

Persuade

6,237

net votes in the plan, from a pool of 6,237

Who. 6,237 voters who split their ticket in recent elections and lean Strickland today.

How. Live conversations on the call list that matters: voters who crossed party lines, plus the undecided. Chung needs to win 50 percent of the ones now leaning Strickland.

Mobilize

497

net votes in the plan, from a pool of 8,196

Who. At least 8,196 people who voted in 2024 but not in 2022, in precincts where Chung's side wins at least 55 percent.

How. Voter ID calls to people who voted in 2024 and skipped 2022, then a ballot chase until each one has voted.

Consolidate

367

net votes in the plan, from a pool of 1,047

Who. Voters who went third party in recent races, in the precincts that lean Chung's way.

How. A direct appeal to voters who went third party last time. They have already shown they will leave the two-party default.

Together: 7,101 net votes against a gap of 43,308. Still 36,207 short. The rest needs a national shift of about 13.3 points that no campaign controls.

Where it is won

What the numbers say that the polls do not

The hidden path.

Beaver Creek (Thurston County) carries the most.

Beaver Creek (Thurston County) gives this plan more net votes than any other precinct: 49. It sits at Chung +30 on our starting line, and 5.1 percent of its voters split their ticket in recent elections.

Yelm 3 (Thurston County) is a turnout target.

Chung's side leads Yelm 3 (Thurston County) by about 21 points on our starting line, and it cast about 408 more ballots in 2024 than in 2022 (an estimate). Roughly that many of its 2024 voters sat out the last midterm; bringing enough of them back nets 29 votes there.

Precinct 28-522 (Pierce County) splits its ticket the most.

Of the precincts in this plan, Precinct 28-522 (Pierce County) has the highest share of ticket splitters: 8.8 percent. That is where a persuasion call is most likely to reach someone open to crossing over.

The honest math.

Every lever at its historical ceiling moves 7,101 net votes. The gap is 43,308. That is the measure of what a strong campaign adds: 2.6 points of margin, and a head start if the national mood breaks.

The evidence

Where voters cross over.

Every dot is a precinct. If no one split a ticket, every dot would sit on the line. The orange ones are where Chung's side lost voters it won further up the ballot.

Precincts: 602
Slope: 0.973
R²: 0.977
Residual SD: 3.2 pts
Crossover precincts: 125

Weighted least squares, one point per precinct, weighted by ballots cast. Orange precincts sit more than one residual standard deviation below the line: Chung's side did worse there in this race than the top of the ticket predicts. Hover any dot for the precinct.

The next 36 days

Voting starts October 16.

Now to October 15
Find them
Voter ID calls across the persuasion list in these precincts. Every conversation tags the voter: with Chung, with Strickland, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list.
October 16 to 22
Persuade
Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 6,237 net votes from people who have crossed party lines before. Every supporter it finds goes straight onto the ballot chase.
October 23 to 29
Bank the ballots
Every registered voter is mailed a ballot by October 16. Ballots count if postmarked by November 3, and drop boxes and county voting centers stay open until 8 p.m. on Election Day. Keep chasing every supporter's ballot until it comes back, so the list of unreturned ballots shrinks every day.
October 30 to November 2
Turn them out
The drop-off voters: people who voted in 2024 and skipped 2022. At least 8,196 of them live where Chung is favored. Mailed ballots must be postmarked by November 3, and drop boxes close at 8 p.m. that day. Voters can still register and vote in person at a county voting center through Election Day.
November 3
Election day
Washington has no polling places: drop boxes and county voting centers stay open until 8 p.m., and voters can register in person and vote the same day. The last calls go to identified supporters whose ballots have not come back, with their nearest drop box in hand.

What has to be true

No wishful thinking.

Official results in this district: Harris carried the 2024 presidential race by 17.9 points; Ferguson carried the 2024 governor's race by 9.5 points; Murray carried the 2022 U.S. Senate race by 13.4 points.

Chung wins 50 percent of the ticket splitters now leaning Strickland.
In Yelm 3 (Thurston County) and Yelm 2 (Thurston County), 35 percent of the people who voted in 2024 but skipped 2022 come back and vote.
It would take a national shift of about 13.3 points toward Chung's side, larger than any midterm swing in recent memory.
No 2026 public poll exists for this race, so the starting line is a weighted blend of official recent results; the first real poll will move it.

The work

2,356 conversations.

That is how many live voter conversations this plan takes: about 44,957 dials to 14,986 households, before the last ballot is cast.

2,356

live conversations: persuasion, voter ID, ballot chase

Call list: every ticket splitter and undecided voter in the targeted places (you cannot tell which way they lean before the call), every targeted drop-off voter, and the reachable third-party voters. About 69 households for every 100 voters on the list, three attempts each, and a 5.24 percent live answer rate per attempt, the per-program average across 1.2 million real 2026 dials in our published benchmarks.
