Elaine Kamarck is a longtime member of the DNC’s rules committee, a scholar at Brookings, a former advisor to top Democrats such as Bill Clinton, Al Gore, and Walter Mondale; and author of “Primary Politics: Everything You Need to Know about How America Nominates Its Presidential Candidates.” On this episode of Playbook Deep Dive, Playbook co-author Eugene Daniels asks Kamarck all of your questions about how the Democratic Party would choose a new nominee should Joe Biden step aside. Topics include: How and when Joe Biden would go about dropping out; if his delegates can rebel against him if he doesn’t; whether or not he can choose a successor; how exactly an open convention would unfold in Chicago; and what she thinks the public’s reaction will be if the Democratic nominee for president is chosen by a handful of party insiders in smoke-filled back rooms.
