Is nobody going to point out that the DNC already had a primary? And that by replacing the candidate last minute, against the will of their voters, the DNC would be acting incredibly undemocratically? Do you want your core voting block to start voting in republican primaries instead? Because throwing out their primary vote is how you get that to happen.

The DNC had a primary, there were multiple candidates, Biden lost the primary in American Samoa. I voted for Biden, he won, if the party elite swap him out last minute regardless of what their primary said, why would anybody care to vote in their primaries?
