You are the first woman in history to be elected vice president of the United States. On July 21, 2024, your running mate, Joe Biden, announces that he will not be seeking reelection. The presidential election will occur on November 5, 2024. You have 107 days. Written with candor, a unique perspective, and the pace of a page-turning novel, 107 Days takes you inside the race for the presidency as no one has ever done before. KAMALA D. HARRIS served as the forty-ninth vice president of the United States from 2021 to 2025—the first woman in American history to hold the office. She began her career in the Alameda County district attorney’s office before being elected district attorney of San Francisco, where her Back on Track program became a national model for reducing recidivism. As California’s attorney general, Harris prosecuted transnational gangs, big banks that defrauded homeowners, and for-profit colleges that targeted students and veterans. She defended the Affordable Care Act, fought for marriage equality, and pioneered the nation’s first open-data initiative in the criminal justice system. In the United States Senate, Harris fought for civil, immigrant, and voting rights, and gained national recognition for her incisive questioning in committee hearings. As vice president, she led efforts to strengthen global alliances and address child poverty, gun violence, student debt, maternal health, economic opportunity, and reproductive rights—casting more tiebreaking votes than any vice president in history, including for pandemic relief and the largest climate investment ever. Throughout her career, she has always fought for the only client she has ever had: the people.
