On 4 August 2026, Democratic voters in Michigan selected Abdul El-Sayed as their candidate for the state’s open Senate seat, narrowly defeating Congresswoman Haley Stevens by roughly 15,000 votes out of almost 1.5 million cast, 48.5 per cent to 47.5 per cent. Mallory McMorrow, who withdrew in July but stayed on the ballot, took 4 per cent. El-Sayed, an epidemiologist and former Detroit health director who lost the 2018 gubernatorial primary to Gretchen Whitmer, campaigned on Medicare for All and on driving corporate money out of politics. He faces Republican Mike Rogers in November for the seat being vacated by the retiring Democrat Gary Peters.
The contest was openly ideological. Stevens, a four-term congresswoman who flipped a suburban district in 2018 and worked on the Obama administration’s rescue of the car industry, was the preferred candidate of the party establishment, endorsed by Senate Minority Leader Chuck Schumer and Governor Whitmer. Her case was electoral rather than philosophical: a moderate, she argued, stood a better chance in a state Trump carried in 2024. El-Sayed campaigned instead alongside Bernie Sanders and Alexandria Ocasio-Cortez. Michigan also runs an open primary, in which any registered voter may take part, so the nominating electorate extended well beyond committed Democrats.
Structurally, the result shows how little control American parties exercise over their own candidates. No national body can impose a nominee, because primaries transfer selection to voters, leaving party leaders to signal preferences through endorsements and money. The money was considerable. OpenSecrets recorded roughly $52 million of outside spending by mid-July, much of it benefiting Stevens, including from groups aligned with the pro-Israel lobbying organisation AIPAC. Since Citizens United v FEC (2010), such groups may spend without limit provided they stay formally independent. El-Sayed claimed he was outspent eleven to one, and won regardless.
What the result reveals is the depth of factionalism within the Democratic Party, and the degree to which polarisation now operates inside parties as well as between them. A margin of one percentage point is not a realignment. It is evidence of a party genuinely divided over whether to answer Trump with reassurance or with economic populism. Results elsewhere that night complicate any simple reading: Missouri Democrats rejected the progressive Cori Bush in favour of Wesley Bell, and Virginia Democrats chose establishment candidates, while in Michigan’s 13th district the democratic socialist Donavan McKinney unseated a sitting congressman. November will do more than any primary to settle which argument prevails.
