107 Days is the political memoir of former U.S. Vice President Kamala Harris, co-written with author Geraldine Brooks. It chronicles Harris’s 2024 presidential campaign, which lasted exactly 107 days after President Joe Biden’s withdrawal, and offers reflections, critiques, and behind-the-scenes glimpses into intra-party tensions, campaign pressures, and personal decisions.
Genesis & structure
Announced July 31, 2025, 107 Days was published on September 23, 2025 by Simon & Schuster. In developing the book, Harris drew heavily on a campaign journal she kept, and Brooks helped shape it into a more narrative structure. The memoir is roughly 320 pages.
The title is literal: Harris’ campaign ran for 107 days — a dramatically short window to build momentum, fundraising, and voter connection.
Themes & revelations
1. The Biden decision & fractures
Harris is sharply critical of how the 2024 presidential cycle unfolded. She argues that leaving the decision to run up to Joe and Jill Biden was “reckless,” particularly given health concerns and a poor debate performance. She describes disappointment and frustration at how her candidacy was handled internally.
2. Internal party dynamics & trust issues
A recurring motif is mistrust — Harris felt sidelined by Biden’s inner circle, undercut in messaging, and treated as a subordinate rather than a co-equal contender. She lays out moments where she felt tokenized or used, and tensions with key Democratic figures surface throughout.
3. Running mate selection & regrets
The book gives a rare look into her vice presidential decision-making. She considered Pete Buttigieg, but ultimately opted for Tim Walz, citing concerns over political optics, balance, and dynamics. But she regrets some elements — including how the ticket was marketed and whether she sufficiently distinguished herself from Biden.
4. Missteps, vulnerabilities & emotional tone
Harris is candid about her own mistakes — poor interview responses, messaging misfires, and struggles with how to speak about identity, values, and policy in a tight timeframe. She also shares emotional moments: public disappointments, moments of isolation, and the personal toll of campaigning under pressure.
5. The campaign’s short lifespan & “what if?”
Because her campaign was brief, Harris emphasizes the structural disadvantages: lack of time to imprint her identity, build ground operations, or sufficiently separate from Biden’s shadow. The book frequently frames key losses as razor-thin, suggesting that small shifts could have changed the outcome.
Reception & critique
Reactions have been mixed:
-
Some reviewers appreciate the candor and fresh look inside a chaotic campaign, seeing 107 Days as bold and revealing.
-
Others criticize it as too defensive or blame-shifting — arguing Harris places too much weight on external failures and not enough on her own miscalculations.
-
The Guardian’s review laments the lack of emotional closure — readers are left with more questions than resolutions.
-
The Los Angeles Times calls it a “postmortem short on hope,” highlighting how grievances dominate tone.
Democratic strategists and party insiders have voiced concern that the memoir might deepen intra-party rifts, calling it a “bunch of finger pointing.”
Implications & future outlook
107 Days is more than memoir — it’s a strategic artifact. The criticisms of Biden’s campaign, the internal tensions, and the framing of Harris’s role all hint at how she may position herself (or not) in future politics.
Some see the book as a way of resetting her narrative, clarifying her identity separate from Biden, or even laying groundwork for future runs. Others fear it may alienate key allies.
Conclusion
107 Days is an intimate, sharp, and divisive read. It gives a front-row seat to one of the shortest presidential campaigns in U.S. history — with all its promise, pressure, missteps, and unresolved tension. For political watchers, historians, and curious readers, it offers both revelations and reflections — though not always the closure one might hope for.
