Top advisors to Joe Biden vehemently cautioned Democratic donors last summer that if Biden were forced to exit the 2024 election due to concerns over his age and competence, the party would make a grave mistake by running Vice President Kamala Harris against Donald Trump, according to a new book. One recipient of such a message from Biden’s top aides described their emphatic stance, stating that pushing Biden out could result in Harris becoming the nominee, which they believed would be a mistake. Despite these warnings, Biden eventually stepped down, and Harris became the nominee. The book, titled “Fight: Inside the Wildest Battle for the White House” by Jonathan Allen and Amie Parnes, offers insights into Harris’s campaign and the internal dynamics within the Democratic party regarding Biden’s suitability for office. The book details how concerns about Biden’s age reached a boiling point following his poor performance at a debate in June, leading to intense discussions and aides defending Biden against calls for his withdrawal. The tension arose from donors threatening to cut off financial support unless Biden stepped down.
