Right now you have 50 states with 50 different ways of selecting and placing delegates. While the national sets the general requirements which includes number per congressional district and super delegates loosely based on party membership or the number of party votes cast for the president in the previous presidential election.
The latter number of delegates waxes and wanes on turnout for that particular election. Also some states list the delegate’s name and affilation while some don’t and some don’t list the delegate at all on their primary ballot.
Then too you have different filing dates. Some states require filing three months ahead of their primary while others perhaps two weeks.
Some don’t even hold primaries but hold caucuses.
On the other hand, putting a lot more weight on delegate allocation to states which actually deliver for the GOP will cause those states to consider no only how they select delegates, but how they allocate electoral votes, probably in a way which would maximize their potential for more delegates.
Under the current system, states which almost never vote GOP (New York, California) have an outsized influence in the selection of the nominee.
