Decisions, Regret, and Loyalty in Harris’s Memoir

107 Days is Kamala Harris’s political memoir, published in September 2025.

The memoir covers the intense 107-day period of her 2024 presidential campaign after President Joe Biden withdrew his bid.

Co-written with Geraldine Brooks, the memoir blends reflection with journal-style entries to create a behind-the-scenes account of a campaign built under extraordinary pressure.

Harris details internal dynamics such as her relationship with Biden and his team, the decision-making around selecting a vice-presidential running mate, and moments she views as missteps, particularly media appearances, perceptions of her loyalty to Biden, and her efforts to distinguish her platform.

She also shares emotional responses: surprise, grief, frustration. The book shows what was happening behind the scenes as challenges mounted, decisions had to be made quickly, and criticism from both outside and inside her party increased.

Stylistically, the memoir balances Harris’s polished political voice with more candid, blunt moments. She does not entirely hold back in describing tensions, regrets, and the ways she felt constrained or undermined.

The narrative does not pretend to offer a triumphant arc; instead it leans into the messiness of politics, the weight of expectations, and the costs of leadership under pressure.

107 Days and Its Role in Shaping Harris’s Legacy

107 Days has received mixed reviews. Supporters and some critics praise the book for its honesty and for giving readers an inside look at what it’s like to run a high-stakes campaign on short notice.

At the same time, many reviews find it disappointing in its lack of closure, its tendency to deflect blame, and its limited self-criticism.

Politically, the book is feeding conversations about Harris’s future, the Democratic Party’s strategic missteps, and the challenge of narratives in presidential politics.

Culturally, 107 Days is significant for capturing a moment of vulnerability at the highest levels of politics. It breaks some of the usual polished veneer, showing the personal cost of ambition, loyalty, grief, and conflict under intense public scrutiny. Its release has also highlighted expectations about transparency from political memoirs and may set a higher bar for how future campaign-insider books are judged.
