Michigan Democrat Mallory McMorrow suspended her campaign for the U.S. Senate on Sunday, narrowing the Democratic primary field to two candidates in a critical race that could influence control of the Senate this fall. McMorrow’s exit comes about a month before the August 4 primary and leaves Rep. Haley Stevens and former public health official Abdul El-Sayed as the remaining contenders.
The primary has highlighted ideological divisions within Michigan’s Democratic Party, with Stevens representing a moderate, establishment-backed faction and El-Sayed appealing to progressive voters. McMorrow had positioned herself between these two camps but was seen by many party members as a long shot. Her departure shifts the dynamics, potentially consolidating support behind Stevens or, alternatively, advancing El-Sayed’s bid.
The open Senate seat is being vacated by Democratic Sen. Gary Peters, making it essential for Democrats to retain it in their efforts to reclaim the Senate majority. The general election opponent is expected to be Republican Mike Rogers, a former congressman who lost to Sen. Elissa Slotkin in 2024.
McMorrow did not provide a specific reason for ending her campaign. In a video posted on social media, she urged supporters to continue working for Democratic victories across the ballot and to help build a stronger party. She also affirmed her intention to remain active in politics and said she would support whoever wins the primary.
Both Stevens and El-Sayed sought to court McMorrow’s former backers. Stevens praised McMorrow’s contributions to state policy and emphasized her own campaign’s goal of defeating Rogers. El-Sayed, who has seen a surge in progressive support, echoed McMorrow’s critiques of corporate influence and establishment politics, accusing party insiders of attempting to marginalize challengers. He invited McMorrow’s supporters to join his movement and framed the contest as a fight against establishment control.
The primary has attracted significant financial involvement. Pro-Stevens spending has been particularly high, with groups such as the United Democracy Project—a super PAC linked to the pro-Israel organization AIPAC—investing over $20 million in television ads supporting Stevens or attacking El-Sayed. Additional political action committees have contributed more than $15 million in favor of Stevens.
The two remaining candidates are scheduled to face off in a televised debate Tuesday, offering Democratic voters a clearer choice between the moderate and progressive wings of the party as they look ahead to the general election.
