 Once Biden receives votes from a majority of the nearly 4,000 delegates, it will become exceedingly difficult to remove him from atop the Democratic presidential ticket. The DNC's current plan is to train state party chairs next week on how to conduct the electronic voting in a secure way. The window for voting is likely to open July 29th, conclude by August 5th. If the working plan for a virtual roll call holds, Biden just has to outlast his party's critics for about two more weeks.
