WASHINGTON — Progressive candidate Abdul El-Sayed held a narrow lead over U.S. Rep. Haley Stevens in Michigan’s Democratic U.S. Senate primary on Tuesday, though the race remained too close to call as votes continued to be counted.

With about 70% of the estimated vote counted, these projections put El-Sayed ahead with 49.8% of the vote, compared to 46.3% for Stevens.

The race has emerged as one of the most closely watched Democratic primaries of the 2026 election cycle, spotlighting divisions within the party between its progressive and moderate wings.

El-Sayed ran on a platform of cutting household costs, increasing access to health care and reducing the role of money in politics. Stevens, who is considered a more moderate candidate, received endorsements from several Democratic leaders and pro-Israel organisations.

Political observers see the race as a measure of whether Democratic voters in a key swing state are embracing candidates who advocate for broader structural changes while distancing themselves from the party’s traditional leadership.

The Democratic nominee will go up against Republican Mike Rogers in the November general election. The race is expected to be critical to the Democrats’ chances of reclaiming the U.S. Senate.

A Test of the Democratic Party’s Course

The Michigan primary also reflects a debate raging within the Democratic Party over U.S. policy toward Israel, an issue that has played out in several congressional primaries this year. Unlike many previous contests in heavily Democratic districts, Michigan's statewide race has broader national implications due to the state's competitive political landscape.

The election is a closely watched indicator of both electoral and policy trends in Michigan, which remains one of the nation's most important presidential battlegrounds and home to one of the largest Arab American populations in the United States.

U.S. Representative Debbie Dingell, who sat out the primary campaign, called on Democrats to come together behind the eventual nominee.

“This race is about how people are hurting,” Dingell said as voting was underway, pointing to rising costs for groceries, petrol, housing and health care as issues likely to dominate the general election campaign.

Recent polling found that favourable views of Israel among Democrats fell from 59% in 2018 to 22% in May. The Michigan contest is also testing broader voter dissatisfaction over economic pressures and perceptions of the Democratic Party establishment, analysts say.
