The primary process is so heavily fucked between superdelegates, and games played by the DNC that it’s pointless to even try.
Or did you forget it was the superdelegates that fucked Bernie in the early primary, as well as all the other games like removing his access to voter roles for a bug that was reported by his staff,
As well as the first few states generally dictate the course of the primary.
You’d have a point if a) every state primaries on the same day, b) superdelegates didn’t exist, and c) the DNC abided by its own rules.
