[Ed. – Oh, what do you know. We were just talking about that. This would be one scenario; one that assumes Biden remains a sort of viable front-runner between now and the rescheduled convention — whatever it consists of — in August. It’s not clear that will happen.]
[I]t’s fair to ask: Is Biden definitely the nominee? Right-wing commentators like Glenn Beck and Tucker Carlson as well as former Bernie Sanders Press Secretary Briahna Joy Gray have speculated Biden will be replaced on the ticket, but how could that happen? Is there a path to nominating someone else?
[I]f they wanted to replace Biden (whether with Cuomo, the veep nominee, or some arrangement of both) Democratic leadership could wait until after the nomination to do so. Then, as they did with Democratic vice presidential nominee Thomas Eagleton in 1972, they could ask Biden to step aside, citing his health. …
With Biden out, the Democratic National Committee, a group of around 350 which is “composed of the chairs and vice-chairs of each state Democratic Party Committee and over 200 members elected by Democrats in all 57 states and the territories,” would vote to select a new nominee.
