That statement posits an entirely different scenario, where the Democratic primary is held as normal, with a prediction about its process and outcome (a prediction I mostly agree with).

I stand by my earlier statement. There will be a Democratic primary vote in every state. There will be challengers on those primary ballots, even if they are minor players or only locally known. The optics of not having one, even if the results of the national Democratic primary are obvious, would be ridiculously bad, and the Republicans and their candidate would latch on to that and call it “fascism.”
