A new book exploring the future of the Democratic Party details how former President Barack Obama helped President Joe Biden secure the 2020 nomination after backing Hillary Clinton in 2016.

Hunter Walker and Luppe B. Luppen, authors of The Truce: Progressives, Centrists, and the Future of the Democratic Party, said sources told them Biden called Obama after it became clear Clinton would lose to Donald Trump in 2016 to say, “Boss, I told you. People just don’t like her.”
