 Biden, of course, has endorsed Harris, which would strongly tip the scales towards unity there. His nearly 3,900 delegates wouldn't be required to back Harris, they write, but they were chosen for their loyalty to him and may be inclined to do what he asks, especially because she is already on the ticket, the ticket the primary voters chose. The virtual vote, they write, is not a typical part of the nomination process. It was largely set up to confirm Biden as the nominee before the state of Ohio's ballot deadline, which falls before the Democratic Convention this year.
