Michigan State Sen. Mallory McMorrow suspended her U.S. Senate campaign Sunday, collapsing the Democratic primary field into a two-way contest between Rep. Haley Stevens and Abdul El-Sayed one month before voters head to the polls. "Today, I'm announcing that I am suspending my campaign for United States Senate," McMorrow said, adding that she was doing so "with a deep, deep sense of gratitude."
The exit reshapes one of the cycle's most consequential races. Republicans hold 53 Senate seats, and Democrats must flip four to retake the chamber. The Cook Political Report rates Michigan a toss-up, and the seat, opened by the retirement of Sen. Gary Peters, now runs through a sharpened ideological binary. The primary is Aug. 4.
A clean ideological split
Stevens, backed by much of the Democratic establishment including Senate Democratic Leader Chuck Schumer, is running as the party mainstream's choice. El-Sayed, a former Michigan health official, has consolidated the progressive lane with endorsements from Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez. Ocasio-Cortez endorsed El-Sayed last week, CBS News reported, in a race framed by both campaigns as a battle over the party's direction after insurgent victories in New York and Colorado.
Endorsements follow the exit
Hours after McMorrow's announcement, Michigan Attorney General Dana Nessel endorsed Stevens on Facebook. Stevens described herself in a statement as "the strongest Democrat to defeat Mike Rogers this November." The winner of the primary will face Rogers, the former GOP congressman who narrowly lost Michigan's other Senate seat to Sen. Elissa Slotkin in 2024.
McMorrow signals a continued role
McMorrow did not endorse a successor. "I may be suspending this campaign, but I am not leaving the fight," she wrote on X, according to CBS News. A person with direct knowledge of the race told PBS NewsHour that the biggest factor in her decision was the recent influx of outside spending boosting Stevens.
The money behind the front-runner
The American Israel Public Affairs Committee has poured millions of dollars into ads supporting Stevens, PBS reported, leaving McMorrow and El-Sayed struggling to keep pace. "We cannot allow the establishment to decide our nominee for us," El-Sayed said. In a May debate, El-Sayed repeatedly went on the offensive against Stevens, who mostly declined to engage directly with him.
Ballots are already in voters' hands. Stevens and El-Sayed meet Tuesday in a televised debate, their first head-to-head since McMorrow's departure and their last major joint appearance before the Aug. 4 primary.
