From what I understood you had to register after each tier. So if you were a assigned county delegate, you had to register separately for the state delegate vote. Which is where the May 2nd deadline comes from. It’s not enough to be declared a delegate in the country proceedings. According to the official documents there are several registrations that must happen. People either didn’t register between the county delegates being assigned or they had incorrect information. I don’t get why they are arguing over the 64 delegates if what the article says about Bernie only getting 78% of his total county delegates seated.
