Probably state by state? I remember when I was complaining about party interference with Bernie, then CO saw which way things were going with Trump, and decided to cancel their primary and award all delegates to his opposition (I don’t remember who was still standing).
Edit: Nevermind I finally clicked the link after opening my big mouth and saw that the map shows no primaries were cancelled in 2024. I’ll leave this as a warning. People, don’t be like me. Click the link before replying.
That’s a risky thing to wish for. Could be awesome! Could be an unwatchable green screen nightmare.
