New York: When Joe Biden phoned Kamala Harris to tell her that he was dropping out of the 2024 presidential race, he said he was just minutes away from announcing his decision to the world. For more than three weeks, Biden had been bucking demands to drop out, and Harris assumed he was going to persevere. But in another sense she felt ready: “I knew I was the candidate in the strongest position to win.”Joe Biden, Kamala Harris and Donald Trump. It’s a question that looms over 107 Days, Harris’ new memoir about her second presidential campaign, though she tries to dispel any doubts by cutting them off at the pass. One refrain in this memoir is how little time Harris had to make her case to the American people.
