Kamala Harris, the former vice president and 2024 Democratic presidential nominee, is once again at the center of the American political conversation—this time, not for a campaign, but for her blockbuster memoir, 107 Days. According to Simon & Schuster, the publisher behind the book, 107 Days sold a staggering 350,000 copies in its first week alone across print, ebooks, and audiobooks. That figure, announced on October 1, 2025, has already prompted a fifth printing, which will bring the number of hardcover copies in circulation to half a million. The publisher projects the book will be the top political memoir of 2025, a rare feat in a market often crowded with post-election retrospectives.
The book’s title refers to the whirlwind 107 days Harris spent as the Democratic nominee for president in 2024, a campaign that began unexpectedly after President Joe Biden withdrew from the race on July 21, 2024. Biden’s exit followed a disastrous debate on June 27, where he appeared confused and slow to respond—a performance many observers attributed to his age. With the clock ticking and little time for a new primary, Harris was thrust into the national spotlight, taking up the mantle against a familiar adversary: former President Donald Trump, who had been running for a return to the White House for nearly a decade.
Harris’s campaign was historic and, by her own account, chaotic. Speaking at The Wiltern in Los Angeles on September 30, 2025, to a crowd of 2,000 supporters—some of whom paid hundreds or even thousands of dollars on the resale market for tickets—she described the election as “unprecedented.” As Harris put it, “I wrote the book for many reasons, but primarily to remind us how unprecedented that election was. Think about it. A sitting president of the United States is running for reelection and three and a half months before the election decides not to run, and then a sitting vice president takes up the mantle to run against a former president of the United States who has been running for 10 years, with 107 days to go.”
Despite the energy and attention surrounding her campaign, Harris ultimately lost to Trump, who secured victory by more than 2.3 million votes—about 1.5% of the popular vote—and an electoral college margin of 312-226. While Trump has claimed his win was a sweeping mandate, Harris pushed back during her LA event, telling the audience, “And by the way, can history reflect on the fact that it was the closest presidential election?” She reminded supporters that other contests, like the 2000 Bush-Gore race, were even tighter, but emphasized the unique chaos and compressed timeline of her own campaign.
In 107 Days, Harris offers both a personal and political account of her brief but high-stakes run. The book is structured as a journal, with chapters dedicated to significant moments in the race. She reflects on Biden’s age and mental sharpness, noting how his image—good or bad—cast a shadow over her campaign. Harris also critiques the priorities of the Biden administration, saying she would have focused first on “affordable childcare, paid leave, extension of the child tax credit,” and other “basic issues facing Americans who need to just get by today,” rather than on infrastructure and semiconductor manufacturing.
Harris’s candor has not gone unnoticed—or unchallenged—within her own party. Some Democrats have bristled at her criticisms, especially regarding her decision not to select Pete Buttigieg as her running mate. In the memoir, Harris claims she doubted Americans were ready for a ticket featuring both a biracial woman and a gay man. She also recounts reaching out to California Governor Gavin Newsom after Biden’s withdrawal, only to receive a terse response that he was “out hiking.” These revelations have sparked debate but have also fueled public curiosity, driving strong book sales and packed appearances across the country.
The book’s success is not solely due to political intrigue. Harris has embarked on a meticulously planned media tour, appearing on major platforms like ABC’s The View and sitting down with Rachel Maddow on MSNBC for her first television interview since leaving office. The tour has included stops in New York, where a launch event was disrupted by protesters over Israeli actions in Gaza, and multiple cities nationwide, with another high-profile event scheduled at The Wiltern on October 28. International stops are also in the works, underscoring the book’s broad appeal.
Harris’s message on tour has been one of resilience and resolve. At The Wiltern, she urged Democrats not to lose heart despite recent setbacks, declaring, “We cannot let our spirit be defeated. Times like this require us to fight fire with fire.” She encouraged continued resistance to the policies of the Trump administration but cautioned that “sometimes the fight takes a while.” Harris also expressed deep disappointment in civic and corporate leaders who, in her view, have capitulated to the Trump administration, saying, “I always believed the titans of industry would be the guardians of our democracy—and I’ve been deeply, deeply disappointed.”
She didn’t shy away from current controversies, lambasting Republicans for what she called their responsibility for the impending federal government shutdown and condemning Trump for sharing a fake AI-generated video targeting Democratic leaders. Harris described Trump as “just a man who is unbalanced, he is incompetent and he is unhinged.” She also spoke of her shock at the climate of fear among journalists, telling supporters, “Journalists are really scared right now. They’re afraid.”
Through it all, Harris’s emotional connection to her campaign and its aftermath was palpable. She compared the pain of her election-night defeat to the grief she felt after her mother’s death, telling the crowd, “I was grieving for my country.” Yet, she remained optimistic, urging supporters to “remember the optimism we felt during those 107 days.”
The memoir’s blockbuster debut puts Harris in rare company. Political memoirs by public figures like Michelle Obama’s Becoming—which sold over 8 million copies globally—Prince Harry’s Spare, and Barack Obama’s A Promised Land have all found eager audiences in recent years. According to Publishers Weekly, 107 Days is poised to join the year’s top ten bestsellers, a testament to Harris’s enduring media and cultural influence, even out of office.
With brisk sales, a headline-grabbing tour, and a willingness to confront both her critics and her own vulnerabilities, Kamala Harris’s 107 Days has become more than just a campaign memoir—it’s a snapshot of an extraordinary moment in American politics, and a signal that Harris remains a force to be reckoned with in the national conversation.
