I like the idea of regional primaries. For example, on a particular date, all the Southeast states have their primaries.
But even with this strategy, someone still has to go last.
It’s a bummer to have a primary when you know who the candidate is gonna be.
Whichever states had the highest percentage of support for the last republican candidate for president should have the first choice of when to hold their primary, followed by the 2nd and on down the line. California (where I am) would probably be close to dead last and the nomination would be a done deal by then.
Reward the states that deliver and punish the states that don’t. It’ll motivate the state GOP groups to try harder in future elections.
