Here’s a scenario.
* Biden accepts the nomination.
* When it’s too late for any primary voting, Joe decides he’s
too old or ill, or whatever, and drops out.
* The DNC declares they must save the day, and Moose gets the
nomination by appointment.
* Kamala can have another squat job, out of the limelight.
Could happen that way. especially if the Dems are unable to derail Trump.
