Underdog UpdateSeptember 26, 2026. Underdog plan published. Starting line: Bera +6.0. Robb Tucker needs 17,447 net votes. Odds 20% today, 27% with the plan.
The number

144,370 votes.

That is half of the 288,739 ballots we expect in this race, plus one. Where Tucker stands today, and what is missing:

133,637 Robb Tucker baseline
151,084 Ami Bera baseline

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

The odds

20% today. 27% with the plan.

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.

How much of what history allows the campaign achieves100%
The plan on this page sits at 100%. Median outcome at this setting: Tucker short by 12,617.

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
3,315
net votes in the plan, from a pool of 3,315

Who. 3,315 voters who split their ticket in recent elections and lean Bera today.

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

Mobilize
784
net votes in the plan, from a pool of 11,695

Who. At least 11,695 people who voted in 2024 but not in 2022, in cities and unincorporated areas where Tucker'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
654
net votes in the plan, from a pool of 1,869

Who. Voters who went third party in recent races, in the cities and unincorporated areas that lean Tucker'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: 4,753 net votes against a gap of 17,447. Still 12,694 short. The rest needs a national shift of about 4.4 points that no campaign controls.

Where it is won

12 cities and unincorporated areas carry 99% of it.

What the numbers say that the polls do not

The hidden path.

Unincorporated Placer County carries the most.

Unincorporated Placer County gives this plan more net votes than any other place: 1,528. It sits at Tucker +19 on our starting line, and 3.0 percent of its voters split their ticket in recent elections.

Loomis is a turnout race.

Tucker's side leads Loomis by about 37 points on our starting line, and it cast about 929 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 118 votes there.

Folsom splits its ticket the most.

Of the cities and unincorporated areas in this plan, Folsom has the highest share of ticket splitters: 3.5 percent. That is where a persuasion call is most likely to reach someone open to crossing over.

Spend it where it counts.

As of June 30, 2026, Bera had $1.83 million in cash on hand to Tucker's $16K. That is exactly why the plan puts every dollar on the few places listed here instead of the whole map.

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 Tucker's side lost voters it won further up the ballot.

The next 37 days

Voting starts October 5.

  1. Now to October 4
    Find them

    Voter ID calls across the persuasion list in these cities and unincorporated areas. Every conversation tags the voter: with Tucker, with Bera, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list.

  2. October 5 to 16
    Persuade

    Second conversations with every undecided and soft voter, built around the one issue they named on the first call. The goal is 3,315 net votes from people who have crossed party lines before.

  3. October 17 to 26
    Bank the ballots

    California mails a ballot to every active registered voter starting October 5. Ballots postmarked by November 3 count if they arrive by November 10, and conditional voter registration is open through Election Day. Chase every supporter's mail ballot request until it is returned, and move supporters to early voting while it is open.

  4. October 27 to November 2
    Turn them out

    The drop-off voters: people who voted in 2024 and skipped 2022. At least 11,695 of them live where Tucker is favored. Ballots postmarked by November 3 count if they arrive by November 10.

  5. November 3
    Election day

    Polls and vote centers are open until 8 p.m. California allows conditional voter registration through Election Day. The last calls go to identified supporters who have not voted, with their polling place in hand.

What has to be true

No wishful thinking.

Official results in this district: Harris carried the 2024 presidential race by 10.1 points; Schiff carried the 2024 U.S. Senate race by 6.0 points; Newsom carried the 2022 governor's race by 1.9 points.

  1. Tucker wins 50 percent of the ticket splitters now leaning Bera.
  2. In Unincorporated Placer County and Loomis, 35 percent of the people who voted in 2024 but skipped 2022 come back and vote.
  3. The national environment moves about 4.4 points toward Tucker's side between now and November 3.
  4. 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

2,190 conversations.

That is how many live voter conversations this plan takes: about 41,801 dials to 13,934 households, before the last ballot is cast.

14K
households on the target list
42K
dials across three attempts
2,190
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.

HyperPhonebank

We run this list.

Calls are the voter ID and ballot chase engine of this plan. They find the persuadable voters and the supporters, so every other dollar lands on the right door. The full call program for this list is an estimated $5,872 at our published rates: 13,934 households, three attempts each.

Professional live callers working exactly these precincts: persuasion on the ticket splitters, voter ID on the fence, ballot chase on every absentee request until it is returned. A live dashboard shows every conversation as it happens. Days to launch, not weeks.
