It’s not every year that a political memoir sweeps the literary world, but former Vice President Kamala Harris’ new book, 107 Days, has done just that. In just seven days since its late September 2025 release, Simon & Schuster announced that Harris’ account of her whirlwind 2024 presidential campaign has sold a staggering 350,000 copies across all formats—including pre-orders, print, ebooks, and audiobooks—according to multiple reports, including a statement from the publisher. This puts 107 Days on a clear trajectory to become the best-selling memoir of the year, with only the likes of Britney Spears, Taylor Swift, and Prince Harry outpacing its first-week sales since 2023.
Jonathan Karp, President and CEO of Simon & Schuster, didn’t mince words in his praise, calling the book “one of the most interesting books ever written about the experience of running for President of the United States” and declaring, “the success of 107 Days proves what a galvanizing and inspiring cultural figure Kamala Harris is.” With the publisher ordering a fifth printing to bring the number of hardcover copies in print to 500,000, the appetite for Harris’ story seems insatiable.
The memoir’s title, 107 Days, refers to the length of Harris’ historic but ultimately unsuccessful campaign for the White House in 2024. After then-President Joe Biden ended his bid for reelection, Harris was elevated to the top of the Democratic ticket—a move that set off a frenetic, 15-week battle culminating in Donald Trump’s November victory. The book details not only the drama and intensity of those weeks but also offers a candid look at the challenges, missteps, and internal party dynamics that shaped her journey.
Harris doesn’t shy away from the heartbreak of defeat. In one of the memoir’s most striking passages, she recounts the moment her campaign manager, Jenn O’Malley Dillon, told her she had lost the race. “We’d planned for everything, it seemed, except the actual result,” Harris writes, laying bare the emotional and logistical shock that followed the campaign’s abrupt end. The sense of vulnerability and honesty in these pages has resonated with readers across the political spectrum, though some observers wonder if the book’s sales are front-loaded by Harris’ most ardent supporters, as noted by Today in Books.
Since the book’s launch, Harris has embarked on a multi-city tour to promote 107 Days, with nearly all stops—such as her recent appearance at The Wiltern theater in Los Angeles—selling out rapidly. On September 29, 2025, Harris addressed a packed house in L.A., striking a tone that was at once defiant and hopeful. “Our spirit cannot be defeated with an election or by an individual or a circumstance. ‘Cause then they’re winning,” she declared, urging her audience to “fight fire with fire” and remain engaged in the nation’s political life. The event, moderated by the hosts of the “I’ve Had It” podcast, was free of the disruptions that had marred her earlier New York City stop and instead featured enthusiastic chants of “MVP! MVP!” from the crowd.
Harris also shared a more personal anecdote about the uncertainty she faced returning home to California after her vice presidency ended. During the January 2025 wildfires that swept through greater Los Angeles, Harris and her husband, Doug Emhoff, were forced to evacuate their Brentwood home. “We actually had a mandatory evacuation of our home. And the evacuation didn’t lift until the 19th (of January). And we were supposed to come back to L.A. on the 20th, so we didn’t actually know if we had a house to come back to,” she told the audience. Once safely home, she spoke of “physically and metaphorically unpacking”—not just boxes, but the emotional baggage and lessons of her campaign.
Throughout her book and public appearances, Harris has been candid about what she believes Democrats need to do differently. She argued that the party must focus more on immediate, tangible needs—like affordable child care, paid leave, and extending the child tax credit—rather than only long-term goals such as combating climate change. Reflecting on the Biden administration’s “Build Back Better” agenda, Harris said she would have prioritized these family-focused policies first to provide relief to Americans “barely getting by.”
Yet, not all of Harris’ reflections have been warmly received within her own party. As Politico reported, some top Democrats—including Pennsylvania Gov. Josh Shapiro, former Transportation Secretary Pete Buttigieg, and California Gov. Gavin Newsom—have bristled at criticisms Harris leveled in the book, particularly regarding the early campaign and her choice of running mate. Harris’ media blitz to promote the memoir, which has included attempts to walk back some of her sharper comments and a refusal to rule out another presidential run, has further fueled tensions among Democrats still stinging from last year’s loss to Trump.
Perhaps most notably, Harris took aim at the Biden White House, alleging that she was saddled with unpopular policy priorities and that negative stories about her office were amplified. In hindsight, she wrote, not pushing Biden to exit the race earlier was “reckless.” Yet, in an appearance on “The View,” Harris insisted that she and Biden maintain “a good relationship and it’s a relationship that is based on mutual respect, having been in the trenches together, and admiration. And it’s sincere.”
Harris didn’t reserve her criticism for fellow Democrats. At her Los Angeles event, she urged the public not to normalize actions by President Trump’s administration since his return to office in January 2025, including mass deportations, attempts to cut health care, and efforts to limit press freedom. She expressed particular disappointment in what she described as the “capitulation” of some universities, law firms, and media companies to the president’s demands, saying, “I always believed that if push came to shove, the titans of industry would be among the guardians of our democracy. And I have been deeply disappointed.” The White House, for its part, has not commented on Harris’ remarks.
Despite the intense scrutiny, Harris has continued to draw crowds at her book tour events, with 15 more engagements scheduled—including another sold-out appearance at The Wiltern in late October, and stops in Houston and San Francisco. The memoir is being published not just in the United States, but also in Australia, Canada, India, and the United Kingdom, reflecting international interest in Harris’ story and the broader implications of the 2024 election.
For those hoping for a hint about Harris’ future political ambitions, she remains coy. After announcing in July that she would not seek the California governorship, she has yet to reveal whether she’ll make another run for the presidency. For now, she seems content to reflect, engage, and encourage Americans to stay vigilant, reminding them, “Enough with the savior complex. … There’s not going to be a Messiah coming to save us. … We’ve got a lot of stars in the (Democratic) Party … and this whole circular conversation—‘Who is the one? What is the one message?’—is so unproductive when we have a lot of work to do. … I’m kind of getting bored with that conversation.”
As 107 Days continues to fly off shelves and dominate political discourse, Harris’ story is clearly far from over. Whether she returns to the campaign trail or not, her memoir has already left an indelible mark on the political and cultural landscape of 2025.
