Arizona · U.S. House · District 8 · November 3, 2026

What it would take for Bernadette Greene Placentia.

Hamadeh starts 13.6 points ahead on our starting line from recent official results. Campaign work can move about 7,578 net votes toward Greene Placentia, a 2.4-point gain. Winning outright would take a 11.2-point national wave on top of that. Here is the plan that makes Greene Placentia the one standing if one comes.

That is half of the 311,214 ballots we expect in this race, plus one. Where Greene Placentia stands today, and what is missing:

134,061 Bernadette Greene Placentia baseline
176,346 Abraham Hamadeh baseline

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

The odds

2% today. 5% 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.

The plan on this page sits at 100%. Median outcome at this setting: Greene Placentia short by 34,704.

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
6,710
net votes in the plan, from a pool of 6,710

Who. 6,710 voters who split their ticket in recent elections and lean Hamadeh today.

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

Mobilize
742
net votes in the plan, from a pool of 11,383

Who. At least 11,383 people who voted in 2024 but not in 2022, in precincts where Greene Placentia'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
126
net votes in the plan, from a pool of 361

Who. Voters who went third party in recent races, in the precincts that lean Greene Placentia'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: 7,578 net votes against a gap of 42,286. Still 34,708 short. The rest needs a national shift of about 11.2 points that no campaign controls.

What the numbers say that the polls do not

The hidden path.

El Caro (Maricopa County) carries the most.

El Caro (Maricopa County) gives this plan more net votes than any other precinct: 172. It sits at Greene Placentia +31 on our starting line, and 4.2 percent of its voters split their ticket in recent elections.

Butler (Maricopa County) is a turnout race.

Greene Placentia's side leads Butler (Maricopa County) by about 18 points on our starting line, and it cast about 972 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 62 votes there.

Palo Verde (Maricopa County) splits its ticket the most.

Of the precincts in this plan, Palo Verde (Maricopa County) has the highest share of ticket splitters: 5.7 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 7,578 net votes. The gap is 42,286. That is the measure of what a strong campaign adds: 2.4 points of margin, and first position if the national mood breaks.

The next 37 days

Voting starts October 7.

  1. Now to October 6
    Find them

    Voter ID calls across the persuasion list in these precincts. Every conversation tags the voter: with Greene Placentia, with Hamadeh, or undecided. The undecided become the persuasion universe; the supporters become the ballot chase list.

  2. October 7 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 6,710 net votes from people who have crossed party lines before.

  3. October 17 to 25
    Bank the ballots

    Arizona mails early ballots starting October 7, and in-person early voting runs October 7 through October 30. Early ballots must be received by 7 p.m. on November 3; a postmark does not count, but voters can drop them off in their county 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 26 to November 2
    Turn them out

    The drop-off voters: people who voted in 2024 and skipped 2022. At least 11,383 of them live where Greene Placentia is favored. Early ballots must be received by 7 p.m. on November 3; a postmark does not count. Voters can drop off a sealed early ballot at a drop box or voting location in their county through 7 p.m. on Election Day.

  5. November 3
    Election day

    Polls are open 6 a.m. to 7 p.m. Arizona has no same-day registration; the registration deadline is October 5. 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: the Republican nominee carried the 2024 House race by 13.0 points; Trump carried the 2024 presidential race by 16.3 points; Lake carried the 2024 U.S. Senate race by 7.6 points.

  1. Greene Placentia wins 50 percent of the ticket splitters now leaning Hamadeh.
  2. In El Caro (Maricopa County) and Butler (Maricopa County), 35 percent of the people who voted in 2024 but skipped 2022 come back and vote.
  3. The national environment moves about 11.2 points toward Greene Placentia'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.
