Take it up with the rules committee.
Delegates are selected based on rules that are part of the party organization.
Parties select delegates, not the general public. I have not idea why the VI gets 9 delegates, but they do.
When the rules become important, no one wants to follow them.
Kind of like tossing out the Constitution when you do not get what you want.
Maybe they get three delegates per island.
All I asked was a question, for a need to know. No need to get short.
