El-Sayed Beats $65 Million: Anatomy of the Michigan Upset

Outspent on the airwaves, opposed by the governor, the minority leader, and the most expensive outside campaign in Senate primary history — Abdul El-Sayed won anyway. Here’s how.

The Associated Press waited until 9:56 on Wednesday morning to call it, more than twelve hours after polls closed. When the call came, the margin was a single percentage point — and the result was the biggest upset of the 2026 primary calendar. Abdul El-Sayed, the epidemiologist and former Detroit health director who lost a governor’s primary to Gretchen Whitmer eight years ago, is the Democratic nominee for U.S. Senate in Michigan.

Strip away the drama of the overnight count and the raw facts are stark. Roughly $65 million in outside money poured into this primary, the overwhelming share of it aimed at stopping El-Sayed and electing Rep. Haley Stevens. Groups aligned with AIPAC alone put more than $30 million behind Stevens. She had the endorsement of Gov. Whitmer, Sen. Gary Peters — whose retirement opened this seat — and Senate Minority Leader Chuck Schumer. On paper, this was the establishment’s race to lose. It lost.

The coalition that money couldn’t buy

El-Sayed’s path ran through a coalition that looked, on paper, like it shouldn’t hold together: the Sanders–Ocasio-Cortez national left, young voters, Arab American and Muslim communities energized in a state with the nation’s most politically significant Arab American population — and the United Auto Workers. That last endorsement mattered enormously. In a state built on carmaking, the UAW gave El-Sayed something no amount of hostile advertising could take away: blue-collar institutional credibility. It insulated him against the “fringe academic” caricature that the ad campaign spent tens of millions trying to build.

Stevens ran the campaign the playbook says to run. A four-term congresswoman who flipped a suburban seat in 2018 and worked on the Obama-era auto rescue, she leaned on manufacturing credentials, tariff politics, and electability. Her supporters’ core argument was never really about ideology — it was that she would run stronger against Mike Rogers in November. Primary voters heard that argument, saturated across every ad break in the state, and narrowly said no.

Why the ads didn’t land

There’s a version of this race where $65 million buries a candidate. It has happened before, in plenty of places. It didn’t happen here, and the reasons are worth dwelling on because they will echo through the rest of the cycle. The advertising against El-Sayed largely avoided the economic terrain where he was strongest — Medicare for All, corporate money in politics, cost of living — and voters appear to have discounted attack volume that never engaged with the things they actually told pollsters they cared about. When one side is talking about your insulin and your rent and the other side is talking about how dangerous the first guy is, saturation stops persuading and starts annoying.

The late Whitmer endorsement of Stevens — delivered in the final month, widely read as a stop-El-Sayed maneuver — may have backfired for the same reason. It confirmed the insurgent’s framing: the entire party apparatus versus a movement. El-Sayed said as much in his early-morning remarks in Detroit, describing a campaign “built on the foundation of what this government was supposed to be in the first place — government of the people, by the people.”

The McMorrow wrinkle

State Sen. Mallory McMorrow’s exit from the race reshaped its final month. She had tried to occupy a lane between Stevens and El-Sayed — a compromise candidate acceptable to moderates and the left alike. When she dropped out, that lane collapsed, the race polarized into a clean two-way fight, and the closing weeks turned openly hostile. Notably, McMorrow was first in line to endorse El-Sayed once the race was called — an early signal that Michigan Democrats intend to close ranks fast, because what comes next is harder than what just ended.

What comes next

Mike Rogers is not a generic Republican. The former congressman and House Intelligence chair came within a whisker of beating Elissa Slotkin in 2024, and he greeted Wednesday’s result by calling El-Sayed a movement of “ideological fanaticism” whose agenda would make Michigan “less safe and less affordable.” The general election message is already written, and it is the same one Stevens’ allies spent $65 million testing. The question that decides control of the Senate may be whether it works better coming from a Republican in November than it did coming from Democrats in August.

For now, one conclusion is unavoidable: the Democratic primary electorate in a critical swing state was offered the establishment’s strongest possible package — money, endorsements, résumé — and chose the movement instead. Whatever happens in November, that fact has already changed the party.
