Another idiotic tool is how delegates are allocated by state. They put about 3/4th of the emphasis on population and 1/4th of the emphasis on the actual ability of the state to deliver electoral votes to the GOP candidate in the fall.
That formula needs to be reversed. There is no way California, who hasn't voted for the GOP presidential candidate since 1988 and probably never will do so again in my lifetime, should get more delegates that Texas who has delivered ever election since 1980.
There are roughly 4.5 times as many convention delegates as electoral votes. Each state should start out with their base number of electoral votes for delegates. Triple weight should be given to their actual ability and past history in delivering electoral votes. Then bonus delegates for things like U.S. senators, congressmen, governors and houses of the state legislature which they control.
With one modification. States that flip to the democrats get their representation halved. States that flip to the republicans get their representation doubled for the subsequent primary. So, say you give CA 1/2 for staying Democrat and TX gets 2x for being republican. All the red states would get 2x delegates and the blue states 1/2.
