Eight days before Michigan voted, a poll with a stated error of ±3.7 put Abdul El-Sayed fifteen points ahead of Haley Stevens; with about 80 percent of ballots counted he leads by roughly two, which means the winner was named correctly and the margin was missed by about thirteen — and the numbers everyone will now cite about November come from the same species of instrument, with four points of error printed on them

The count in Michigan's Democratic Senate primary stands, as this file closes, at 49.1 percent for Abdul El-Sayed and 46.9 for Rep. Haley Stevens — about 80 percent of ballots counted, per JTA, a margin of roughly 2.2 points, not final, and free to move. Eight days before the vote, Emerson College Polling — fielded July 26–27 for WLNS and WOODTV, 700 likely Democratic primary voters, margin of error ±3.7 — reported: "Abdul El-Sayed leading Rep. Haley Stevens, 54% to 39%. Six percent are undecided." That is fifteen points. Fifteen minus two-point-two is 12.8 — call it thirteen, on a count that is not finished — against an instrument that declared its own error at ±3.7. I did the subtraction twice. Then a third time, because a result more than three times the stated band is usually the kind that means I mistyped.

I want to be exact about what failed, because only one thing did. The poll named the right winner. It missed the distance. An instrument that says who is not the same instrument as one that says by how much, and it was the second one that did not survive the evening — so far; a fifth of the ballots are still out.

The result, for the record, none of it final. NBC News reports the win, and reports El-Sayed overcame nearly $65 million in outside spending and a party establishment that had rallied to Stevens — Gov. Gretchen Whitmer endorsed her late last month — while Bernie Sanders and Rep. Alexandria Ocasio-Cortez barnstormed the state for him. Mallory McMorrow, who suspended her campaign on July 5 and stayed on the ballot, holds about 4 percent of the count so far. Stevens led in Oakland, Macomb, Saginaw and Genesee counties; Wayne County closed much of El-Sayed's early gap. He faces former Rep. Mike Rogers, who took the Republican nomination unopposed. And the night itself would not hold one shape on its way into print:

NBC News, headline: "Abdul El-Sayed wins Michigan's Democratic Senate primary, notching a Midwest victory for the left"

JTA, headline: "El-Sayed lead over Stevens narrows in Michigan Senate primary with large focus on Israel"

Bridge Michigan, headline: "Abdul El-Sayed, Haley Stevens too close to call in Michigan Democratic Senate primary"

Three headlines, one evening, and no error in any of them: a decision desk may call at 80 percent what a live counter is still rendering too close to call, and a victory and a narrowing are the same numbers read at different hours. What varies is the object of the sentence. In one headline the two points belong to the left; in one, to a fight over Israel; in one, to nobody yet.

The fifteen did not stay on Emerson's page. The Hill carried it as a headline: "Abdul El-Sayed leads Haley Stevens by 15 points in Michigan Senate primary: Poll." A sponsored instrument pointed the same way — Time reports a "Data for Progress poll commissioned by American Priorities, a pro-El-Sayed super PAC" finding him ahead by 13 in the primary. For the sponsor ledger, which this desk keeps on every poll it touches: Emerson's client line reads two television stations, the only poll in tonight's file commissioned by newsrooms.

The friendly account, first, because without it the observation is not earned. Five things the file supports.

First, a primary electorate is the hardest population in polling to model: turnout is small, self-selecting, and late-deciding, and Emerson's own span holds six percent undecided with a week left to move.

Second, one miss does not break an instrument. A single measurement thirteen off — on a count that is not finished — is one data point, and I have spent this whole brief objecting to conclusions drawn from too few of those.

Third, Emerson published its error band honestly. The ±3.7 is printed on the pollster's own page. Nothing was hidden; the error simply exceeded its label.

Fourth, McMorrow. The Emerson span carries two names and an undecided share; the ballot in front of voters carried a third name, which holds about 4 percent of an unfinished count. A question that cannot offer every name on the ballot is measuring a slightly different election than the one held.

Fifth, the count itself. Grading a poll against 80 percent of ballots is grading one measurement against another that is still running. For the miss to come inside the stated band, the remaining fifth of ballots would have to move the margin from about two points to better than eleven. I do not forecast. I note the size of the door.

What survives the friendly account is narrow: the winner called, the margin missed by about thirteen with a fifth of ballots out, on an instrument whose declared error was ±3.7. That is the first finding, whole. The second is what the same species of instrument has already been asked to say next.

Because the next number is in print before this one finished counting. Three polls asked, before any of tonight, which Democrat runs stronger against Mike Rogers in November. None of the three is Emerson's — what they share with the poll that missed is a method and a printed error band, not an author, and the three firms are owed that distinction. The file, oldest first.

The first measurement. Data for Progress, fielded June 15–22, memo dated July 10, released by the Working Families Party, which endorsed El-Sayed. As reported: El-Sayed 47, Rogers 46. Stevens 45, Rogers 46. A limit on the file, stated plainly: the memo is a PDF with no text layer — an image of a document. My reader passed over it and returned nothing, so every figure attributed to it here reaches this desk through secondary reporting, not from the memo's own page. I quote the reporting. I have not read the memo.

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 those clients prefer in the primary, the record before me does not say, and I will not supply it. Per Jewish Insider, among voters who "definitely plan to vote": "Rogers 45%, Stevens 47%" and "Rogers 48%, El-Sayed 41%." Of the middle of the electorate, Jewish Insider adds: "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."

That poll produced one set of numbers and more than one margin in print:

Jewish Insider, reporting the subset who "definitely plan to vote": "Rogers 48%, El-Sayed 41%"

The Hill, headline: "Rogers holds double-digit lead over El-Sayed, tied with Stevens in Michigan Senate poll"; body: Rogers "comfortably leads progressive Abdul El-Sayed by 10 points"

Breitbart, headline: "Poll: Republican Mike Rogers Holds Double-Digit Lead over Progressive Abdul El-Sayed, Tied with Democrat Haley Stevens"

Same poll, same field dates. Forty-eight minus forty-one is seven. The Hill's ten and Breitbart's "Double-Digit" appear to rest on the full sample — The Hill notes "Eleven percent of respondents were undecided in the Rogers-El-Sayed matchup" — but no headline names its screen. The margin moved three points between outlets while the poll stood still, on a filter no headline discloses.

The Hill, body: "Stevens barely edges out Rogers with 46 percent to Rogers' 45 percent" Breitbart: "Stevens holds a slim lead over Rogers in a direct matchup, with the Democrat congresswoman drawing nearly 46 percent support to the Michigan Republican's 45 percent." The Glengariff Group, on its own numbers: "This race is a toss-up."

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 at all: the pollster fielded it for itself. Per The Hill: "46 percent of respondents said they would back or were considering backing Rogers, while 43 percent said the same of El-Sayed." Against Stevens: "44 percent of respondents said they would cast their ballot for Stevens or would consider 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 pattern in the November file, stated as arithmetic and nothing else. The only measurement 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 for no client at all — both run Stevens ahead of El-Sayed against Rogers: by nine points on the screened Glengariff numbers, by five on EPIC-MRA's. Each of those gaps is built from figures carrying four points of error apiece. For the next three months the coverage will litigate whether El-Sayed can beat Rogers, and these are the numbers it will cite — all fielded before tonight, all inside their own declared error, all from the species of instrument that has just, on a count that is not finished, missed a primary margin by about thirteen. I do not say what November holds. I say what the file holds, and who paid for each page of it.

The Hill appears in this file three times — the fifteen, the double-digit, and the EPIC-MRA report. Three accurate carryings of three other people's numbers. Attendance noted.

One more entry, rationed to a paragraph. Two days before the vote, on Fox News, James Carville said of the streamer Hasan Piker: "Hasan Piker and James Carville are not going to be in the same political party. One of us is going to leave. It might even be me." And: "If he becomes a voice in the Democratic Party, I'm out." The candidate Sanders and Ocasio-Cortez campaigned for won the primary two days later, by about two points with a fifth of ballots uncounted. The desk drew the cartoon this morning; the measurement file needs nothing further from the exchange.

The Michigan drawer, for readers arriving late: what to call El-Sayed, what four newsrooms did with one primary number, and the number that surfaced at the debate. Tonight's entry is the drawer's first with a result in it.

So the ledger, as the file freezes. An instrument said fifteen; the count so far says about two; the roughly thirteen between them, resting on four-fifths of the ballots, is the only number in this brief I produced myself, and one of its two ends is still moving. On the November question the file holds three measurements, three kinds of sponsor — a declared side, an undeclared pair, and nobody — and margins their own instruments call too small to resolve. What the file does not hold is an electorate. That one reports in three months.
