#MSNBC talking about some voices in the Democratic party calling for a "mini-primary" before the convention, or at the convention.
There are no mechanisms for this.
The DNC would have to hold a vote to change the convention rules. Why would they do that? It would only introduce more chaos.
My guess is that #Biden will address the convention, release his delegates, and ask them to vote for #Harris.
I don't think the DNC leadership will tolerate any other nominees.

I don't think it's going to be that difficult nominating Harris. The primaries were winner-takes-all in most states, so there are very few delegates who weren't all-in for Biden. That meant being all-in for the status quo, and that's now Harris. Hard to imagine more than 50% will break ranks with that. Inertia is powerful.
VP choice will be interesting, though.
