A reasonable and fair system would be to divide the US into regions. The primaries for every state in each region would be on the same date. The order in which the regions would run their primaries would be cycled over time.

Why is FedGov involved in primaries at all? Let the parties run their own primarier 100% - only gov interference is verifying signatures for main ballot eligibility and provided public voting locations like firehouses or libraries or whatnot.

But each party should determine their own primary schedule, and they should start with the most party-friendly States. Dems and Repubs should end up running primaries almost complete opposite order from each other.

If the RINOs are in control, then the Dems and Pubbies can run parallel primaries.
