Please clarify your interrogatory.
Here's a simple primer for you.
1. If a state is winner take all, that is fair.
2. If districts give 2 delegates to a winner and 1 to a runner up. That is fair.
3. If a state gives out delegates proportionally, that is fair.
4. Any mix or 1,2, and 3 is fair.
5. If the makeup of a state's delegates is not representative of actual votes, and does not meet 1, 2, 3, and/or 4 above...it is unfair.
6. Finally, folllowing rules that allow voters to be disenfranchised AFTER a vote, or without a vote, is innately unfair...and grossly unethical.
Hope that helps.
