Abdul El-Sayed, Haley Stevens square off Tuesday in Michigan Democratic primary

Michigan Democratic voters will choose between Abdul El-Sayed and Rep. Haley Stevens as their Senate candidate on Tuesday in a pivotal primary election. Stevens, a moderate Democrat, and El-Sayed, a progressive former public health official, are competing for the seat being vacated by Democratic Sen. Gary Peters at the end of this Congress.

The outcome could determine control of the Senate for the next Congress and impact the Democratic Party's direction. El-Sayed has received endorsements from progressive figures like Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez, while Stevens has support from Governor Gretchen Whitmer and former Senator Debbie Stabenow. A win for El-Sayed would bolster the left flank of the Democratic Party, which has recently achieved upsets in New York and Colorado.

Michigan, a bellwether state in national elections, saw Trump win by a narrow margin in 2024 after losing to Biden in 2020 and by less than a third of a percentage point in 2016. The primary results will offer insight into voter sentiment two years before the next presidential election. Stevens' campaign claims she has the best chance to defeat the Republican nominee, former Rep. Mike Rogers, in the general election.

Michigan is a critical state for Democrats to win if they aim to regain a Senate majority, and a Republican win would be crucial for maintaining control of the chamber. The contest between El-Sayed and Stevens has been contentious, with the candidates clashing over issues such as AI data centers and U.S. foreign policy, particularly aid to Israel.

El-Sayed portrays himself as a moderate alternative to Stevens, who Stevens' supporters accuse of being an extremist.
