This book examines the outcome, dynamics, and lessons of the 2020 Democratic Primary. The authors examine how Joe Biden separated himself from a crowded field of candidates, the role that primary rules played in this process, the influence of gender and race on the primary campaign, new developments with the Iowa Caucuses and national party conventions, and what all this could mean for the 2024 election.
