The race for Michigan’s open U.S. Senate seat has taken a dramatic turn as state Senator Mallory McMorrow, one of the Democratic frontrunners, faces mounting scrutiny over her residency history and a sweeping purge of her social media posts. With the August 4, 2026, primary fast approaching and Democrats banking on Michigan as a linchpin in their fight to retake the Senate, the controversy has injected fresh uncertainty into an already fiercely competitive contest.
According to CNN, the controversy erupted when it was revealed that McMorrow deleted thousands of tweets—approximately 6,000 prior to 2020—many of which touched on sensitive political and personal topics. Among the deleted posts were remarks critical of the rural Midwest, expressions of nostalgia for California, and admissions that she continued to vote in California after claiming she had moved permanently to Michigan. The deletions came to light after a 2025 New York Post story highlighted McMorrow’s disparaging remarks about Michigan and "Middle America" following Donald Trump’s 2016 election victory. Archived snapshots from the Internet Archive’s Wayback Machine showed that her X (formerly Twitter) account had over 20,000 tweets in 2022, but now displays around 13,900.
At the heart of the controversy is a question of timing and intent. In her 2025 memoir, McMorrow wrote that she "relocated permanently" to Michigan in 2014. Yet, as CNN’s KFile and other outlets reported, she described herself as a California resident as late as July 2016, referenced voting in California’s June 2016 Democratic primary, and maintained ties to California Congressman Ted Lieu. Public records show she registered to vote in Michigan only in August 2016. Instagram posts further complicate the timeline, indicating she was vacating her Los Angeles apartment as late as March 2016.
McMorrow’s campaign has sought to downplay the deletions, with spokesperson Hannah Lindow describing the move as “pretty standard for candidates.” Lindow explained, “Mallory’s move from California to Michigan was a process that was not complete until mid-2016. She remained registered to vote in California during that time and voted absentee in June 2016. She considers 2014 the start of that move.” The campaign also emphasized McMorrow’s record in Michigan, noting her eight years of legislative service and her role as Senate majority whip. “These are normal tweets by a normal person,” Lindow told CNN. “As Michigan’s Senate majority whip, Mallory has spent the past eight years fighting and delivering to make people’s lives better: higher wages, universal pre-K, no kid going hungry in schools, comprehensive gun violence prevention laws, and more. And she’s tweeted about that too.”
Still, the content of the deleted tweets has fueled criticism from rivals and raised eyebrows among voters. Some posts revealed a progressive bent, including support for Black Lives Matter, contemplation of a future without cars (“Pushing for [a] future where we don’t own cars… Cars are dead,” she joked in one thread), and comparisons between Trump’s America and Nazi Germany. Others were more lighthearted or self-deprecating about Michigan’s weather (“Yesterday it was nearly 50 and now the sky is just shitting ice on everything. I don’t like you, Michigan,” she wrote in March 2016). The campaign stood by her weather-related comments, telling CNN, “The Michigan sky does in fact sometimes shit ice. She stands by that.”
One particularly striking deleted post, dated December 2016, described a dream in which the U.S. split into “The Ring” (the coasts plus Canada, Mexico, and parts of Michigan and Texas) and Middle America, with Obama as Prime Minister and everyone given $1,000 and six months to pick a side. McMorrow’s campaign clarified that this was an actual dream, not a policy proposal or a literal wish.
The controversy over McMorrow’s residency and voting record has played directly into the hands of her opponents. Abdul El-Sayed, a physician and former Detroit public health director, and U.S. Rep. Haley Stevens are both vying for the Democratic nomination in what Emerson College polling describes as a dead heat: McMorrow and El-Sayed are tied at 24% each, with Stevens close behind at 18%. The stakes are high—Michigan is one of only two states with Democratic-held Senate seats in 2026 that Donald Trump won in 2024, making it a must-win for Democrats hoping to regain control of the chamber.
The questions about McMorrow’s residency are not merely academic. Under California law, only state residents are eligible to vote in California elections, with residency defined as a voter’s established domicile and intent to remain. In 2024, McMorrow herself called out a Twitter user for voting in a state they no longer lived in, writing, “So you moved for work and live in California but are registered somewhere you no longer live?…that’s illegal.” Now, her own actions from 2016 have become a flashpoint for critics.
Despite the controversy, McMorrow’s campaign has received strong support from her home state of New Jersey, where she grew up in Readington Township and graduated from Hunterdon Central Regional High School. On May 13, a fundraiser in Asbury Park, New Jersey, will rally support for her Senate bid. Senate Majority Whip Vin Gopal and other prominent New Jersey Democrats are hosting the event, underscoring the national significance of Michigan’s Senate race. “In New Jersey, we are doing our part to help Democrats win back control of Congress, and Michigan is a key place for that to happen by supporting various candidates at the national level,” Gopal said. “Mallory is one of those candidates.”
If McMorrow wins, she would become the fourth U.S. Senator to have grown up in New Jersey, joining Cory Booker, Andy Kim, and Mark Kelly. She first won her Michigan State Senate seat in 2018 and quickly rose to become majority whip. Her campaign has highlighted her legislative achievements and endorsements from auto unions, seeking to counter criticism that her earlier musings about a future without cars were at odds with Michigan’s manufacturing identity. “Mallory started her career as a car designer and doesn’t want to ban cars. She’s been repeatedly endorsed by auto unions,” her spokesperson told CNN.
Michigan’s Senate race is shaping up as one of the most consequential and closely watched contests of 2026. With Senator Gary Peters stepping down after twelve years, the seat is open for the first time in nearly two decades. Although Donald Trump carried Michigan in both 2016 and 2024, the state has not elected a Republican to the U.S. Senate since 1994. Democrat Elissa Slotkin narrowly won an open Senate seat in 2024, highlighting the state’s swing status and the razor-thin margins at play.
The controversy over McMorrow’s deleted tweets and residency history has added another layer of intrigue to a race already defined by shifting alliances, evolving political identities, and the high stakes of Senate control. As the primary draws near, Michigan voters—and the nation—will be watching closely to see whether McMorrow’s explanations satisfy concerns or whether the episode leaves a lasting mark on her candidacy.
With the outcome still uncertain, one thing is clear: in Michigan’s pivotal Senate race, every word, every tweet, and every vote counts.
