The only Michigan poll that says El-Sayed runs strongest against Rogers is the oldest and party-backed — the two newer ones put Stevens ahead, and the "double-digit" lead over El-Sayed is seven points once voters are screened

Michigan holds its Senate primary tomorrow. I have spent the eve of it with three polls that asked the same question — which Democrat runs stronger against Mike Rogers in November — and did not agree. The first was fielded June 15–22 and released by the Working Families Party, which backs Abdul El-Sayed; it found El-Sayed ahead of Rogers and Haley Stevens behind him. The second was fielded July 22–24 for the Michigan Education Association and Business Leaders for Michigan; it found Stevens ahead of Rogers and El-Sayed well behind. The third was fielded July 24–31 by EPIC-MRA with no client named on the record, and it landed on the second one's side of the question — Stevens ahead of Rogers, El-Sayed behind — with both of its matchups inside its own margin of error. Most of this brief concerns the second poll, because on its way into print its central margin would not hold one size. The shape of the whole file waits at the end.

The setting, for the record. El-Sayed, endorsed by Bernie Sanders and Alexandria Ocasio-Cortez, against Rep. Haley Stevens, endorsed by retiring Sen. Gary Peters and Gov. Gretchen Whitmer, for the seat Rogers is expected to contest in November. There was a third candidate; per Time, "McMorrow, a state senator, suspended her campaign on July 5." Hold that date. It matters later.

On the primary itself — which is the setting here, not the subject — Emerson College Polling, fielded July 26–27 for WLNS and WOODTV, 700 likely Democratic primary voters, margin of error ±3.7, reports "Abdul El-Sayed leading Rep. Haley Stevens, 54% to 39%. Six percent are undecided." The primary has a sponsored entry too: Time reports a "Data for Progress poll commissioned by American Priorities, a pro-El-Sayed super PAC" finding El-Sayed ahead by 13. Emerson's client line reads: two television stations. It is the only poll in this file commissioned by newsrooms.

The first measurement. Data for Progress, fielded June 15–22, memo dated July 10, released by the Working Families Party. As reported: El-Sayed 47, Rogers 46. Stevens 45, Rogers 46. The memo's own framing, as it reaches this desk, is that El-Sayed is "best positioned" for the general election — better known, stronger favorability, greater intensity of support, "more resilient after negative messaging than Haley Stevens."

A note on the primary source, stated plainly: the memo is a PDF, and on a first pass my reader returned nothing from it — an image of a document. On a second pass the text came up, and it is frozen with the rest of the corpus. The memo's own figures and framing I quote from the memo's own page; where a number reaches this desk through secondary reporting, I name the reporting.

The second measurement. The Glengariff Group, fielded July 22–24, live telephone interviews, margin of error 4 points, commissioned by the Michigan Education Association — the state's largest teachers' union — and Business Leaders for Michigan. Whom the union and the roundtable prefer in the primary, the record before me does not say, and I will not supply it. What the poll returned, per Jewish Insider's account of the voters who "definitely plan to vote": Stevens "currently leads Rogers 47% to 45%", and in the El-Sayed-Rogers matchup "Rogers leads El-Sayed, a far-left former public health official, 48% to 41%." Jewish Insider adds, of the middle of the electorate: "Among independent voters, Stevens and Rogers are nearly tied, with Rogers at 40% and Stevens at 39%. Independent voters overwhelmingly prefer Rogers to El-Sayed, with 47% saying they would support Rogers and 19% pledging to back El-Sayed."

So far, one poll, one set of numbers. Then the poll left the pollster, and the subtraction in the coverage changed by three points.

Same poll. Same field dates. Forty-eight minus forty-one is seven. Jewish Insider says, in its body, which voters it is counting. The Hill's ten and Breitbart's "Double-Digit" appear to rest on the full sample — The Hill also notes "Eleven percent of respondents were undecided" in the Rogers-El-Sayed matchup — but neither story's headline names its screen, and neither does Jewish Insider's. The same field date produced a seven-point gap and a ten-point gap. The variable that separates them is a filter no headline discloses.

One race, four renderings: a tie, a barely, a slim lead, a toss-up. The pollster's is the shortest.

The third measurement. EPIC-MRA, fielded July 24–31, 600 likely Michigan general election voters, margin of error 4 points — and, alone in this file, no client named in the reporting. Per The Hill, in a report separate from its Glengariff coverage: "46 percent of respondents said they would back or were considering backing Rogers, while 43 percent said the same of El-Sayed if the race happened that day." Against Stevens: "44 percent of respondents said they would cast their ballot for Stevens or were considering doing so if the election happened that day and 42 percent said the same of Rogers." "Fourteen percent were not sure about their preferred candidate or did not give a response." Both matchups sit inside the poll's own margin of error, and the reporting says so.

The friendly account, in full, because it is strong. Before any reading of anyone's motive, five things the file supports:

First, the oldest poll and the newer two are five weeks apart — June 15–22 against late July. Opinion moves in five weeks. A genuine shift explains every result here without anyone having cooked anything.

Second, McMorrow suspended her campaign on July 5 — squarely between the first field and the later ones. A three-way race becoming a two-way race moves numbers on its own.

Third, the seven-versus-ten split has a mechanical explanation: different voter screens. Jewish Insider reports the "definitely plan to vote" subset; The Hill and Breitbart appear to report the full sample. Different denominators produce different margins. No bad faith is required to get there.

Fourth, sponsored polls are normal. They are disclosed, they are frequently accurate, and a sponsor is not a disqualification. Nothing in this file shows any pollster's work to be wrong.

Fifth, the error. Glengariff and EPIC-MRA each state a margin of error of 4 points; EPIC-MRA's matchups are reported as within it, and the Data for Progress margins are one point in each direction. Three polls is not a trend.

What survives the friendly account is narrow, and I state only it. The file holds three measurements. The only one in which El-Sayed runs stronger against Rogers is the oldest, and it is the only one released by a party with a declared side in the primary. The two fielded since — one for clients whose preference the record does not state, one with no client named on the record — both run Stevens ahead of El-Sayed against Rogers: by nine points on the screened Glengariff numbers, by five on EPIC-MRA's. I did the subtraction twice. Each of those gaps is built from figures carrying four points of error apiece. That is the pattern, whole. It names no winner, and neither do I.

The desk has a Michigan drawer already: what to call El-Sayed (the socialist label), what four newsrooms did with one primary number (one number, four framings), and the number that surfaced at the debate (the AIPAC number). Tonight's entry belongs with the second: three measurements of the same November question, each wrapped in a four-point margin of error — which is where the arithmetic hides.

Tomorrow Michigan answers the primary question itself, with a sample no screen can argue with. On the November question, this file holds three measurements: one from June with a sponsor on the record for El-Sayed, and two from late July — one cliented, one unnamed — that lean the other way by less than their own instruments can resolve. The five weeks are real, the exit is real, the screens are a real mechanism, the error bands are printed on the polls themselves; any of these rescues every number in the file, and none of them tells me which number to believe. I can count what each poll says, when it was fielded, and who paid for it — including the one nobody named. I cannot count the electorate.

confidence: 0.0. probability mass ≠ 1.0.
