Abdul El-Sayed narrowly defeated Rep. Haley Stevens in Michigan's Democratic primary for US Senate, overcoming a spending disadvantage of more than 8 to 1 and opposition from his party's establishment to claim the left's most significant victory of the midterm cycle — and set up a November contest that could decide control of the chamber.

With 99% of the expected vote counted, El-Sayed led Stevens by fewer than 15,000 votes out of more than 1.5 million cast, a margin of roughly one percentage point. The race was called Wednesday, about 12 hours after polls closed, following a drawn-out count in Wayne County, home to Detroit. State Sen. Mallory McMorrow, who dropped out weeks before the election but remained on the ballot, drew 4%.

"In the words of Muhammad Ali, we shook up the world," the 41-year-old former Detroit health official told reporters after the race was called. "It turns out that you can spend as much money as you want on lies, but it doesn't make them true."

The result was far closer than late polling suggested — one survey released after the final debate showed El-Sayed ahead by 15 points — and it leaves both wings of the party bruised heading into a general election against former Rep. Mike Rogers, the Trump-backed Republican seeking the seat being vacated by retiring Democratic Sen. Gary Peters. If elected in November, El-Sayed would become the first Muslim senator in US history.

Beating the Establishment and Its Money

More than $80 million was spent on the race, making it the most expensive Democratic Senate primary on record. The imbalance was stark: $7.4 million went toward advertising supporting El-Sayed against $64.7 million for Stevens, including more than $30 million from the United Democracy Project, the super PAC aligned with the American Israel Public Affairs Committee, which sought to stop a candidate who has called for ending US military aid to Israel.

Stevens, a four-term congresswoman from suburban Detroit, carried endorsements from Senate Minority Leader Chuck Schumer, Gov. Gretchen Whitmer, Peters, and former Sen. Debbie Stabenow, and ran on protecting American manufacturing, lowering healthcare costs, and her record as a pragmatic legislator. "It's a Michigan moment for me," she said, playing down the race's national overtones.

El-Sayed, backed by Sens. Bernie Sanders and Elizabeth Warren and Rep. Alexandria Ocasio-Cortez, ran under the slogan "Money out of politics. Money in your pockets. Medicare for All." The son of Egyptian immigrants and a Rhodes Scholar, he cast the outside spending against him as proof of his central argument about a corrupted political system. "We'll have taken $70 million on the chin and kept fighting back," he told supporters at Detroit's Majestic Theatre as the count dragged past midnight.

The returns showed where he built his coalition. El-Sayed led by more than 20 points in counties with the highest shares of young adults, won medium-size cities such as Grand Rapids and Ann Arbor by 11 points, and stayed close enough in suburbs and rural areas — where Stevens held modest edges — to protect his lead. "Have you ever heard of a candidate in a major race getting outspent nine to one, taking on the entire establishment and winning?" Sanders said afterward. "I cannot recall somebody having done that."

The primary also became a proxy fight over the party's posture toward Israel. Stevens, a longtime pro-Israel lawmaker, never distanced herself from AIPAC or criticized Israel's conduct in Gaza, a stance one Democrat involved in the race said left her "caught a little bit off guard" by how much of a liability the group's backing had become. AIPAC said Wednesday its members "remain determined to ensure that voters reject Dr. El-Sayed and his radical anti-Israel agenda in November," while noting wins elsewhere by candidates it supported, including Missouri Rep. Wesley Bell's defeat of former Rep. Cori Bush.

Republicans Move Fast to Define the Nominee

The Republican response arrived within hours. President Donald Trump celebrated the outcome on Truth Social, calling it "great news for the Republican Party" and labeling El-Sayed a "Communist loser who hates Jews and Israel" whom he believes will be easier to beat than Stevens.

The National Republican Senatorial Committee released a digital ad branding El-Sayed "the most radical Senate candidate in America," using his full name and pairing it with a clip of him declaring, "I'm pretty damn dangerous." Republican National Committee Chairman Joe Gruters likened him to New York City Mayor Zohran Mamdani, saying he "embodies the socialist takeover" and citing his support for abolishing Immigration and Customs Enforcement and raising taxes.

Rogers, a former FBI agent who chaired the House Intelligence Committee and narrowly lost the state's other Senate seat to Elissa Slotkin in 2024 by three-tenths of a point, seized on El-Sayed's campaign appearances with Twitch streamer Hasan Piker, who once said America "deserved" the September 11 attacks. "I spent years hunting terrorists and bringing Osama bin Laden to justice," Rogers said. "Never in a million years did I think that I would be running against someone who believes America deserved 9/11."

El-Sayed hit back in his own fashion, accusing Rogers of a political identity crisis. "He's both the worst of the neocon era and the worst of the MAGA era," he said, calling his opponent a "corporate sellout" and jabbing that Rogers should move back to Florida, where he lived earlier this decade. "Mike, I know you're listening. Mike, we are coming for you."

A November Test for the Left in a Purple State

El-Sayed's win extends a run of progressive victories this cycle, but its significance lies in the terrain. While candidates aligned with the Democratic Socialists of America have flourished in deep-blue districts, Michigan is a swing state of more than 10 million people that voted for Trump in 2016 and 2024. Tuesday's primaries also delivered wins for progressive state Rep. Donavan McKinney over pro-Israel incumbent Shri Thanedar, climate organizer William Lawrence in a district north of Detroit, and Rep. Rashida Tlaib.

The general election polling picture is unsettled. The RealClearPolitics average shows Rogers with a narrow lead and more than 10% of voters undecided, while other recent surveys have put the Republican's advantage in double digits. Democrats view the seat as essential to any path back to a Senate majority, and Republicans see Michigan as one of their few pickup opportunities.

El-Sayed moved quickly toward party unity, praising Stevens as "one of the most committed public servants that you'll ever meet" and saying their differences "pale in comparison to what unifies us." McMorrow joined him at his first post-election event, and former Transportation Secretary Pete Buttigieg planned to rally with the nominee Friday. Whether the establishment he spent months attacking reciprocates — and whether his coalition of young, highly educated, and Arab American voters scales to a statewide general electorate — will determine if Tuesday's upset becomes something larger. "We are not a purple state," El-Sayed told supporters as the votes trickled in. "We are a state in need of a movement to take our politics back."
