I've always advocated for three sets of primaries (50 primaries in each state) all on the same day. Hear me out...
So the first set of primaries the last Tuesday in January. This will separate the pretenders from the serious candidates.
Another set of primary the last Tuesday of March. This will narrow the field to maybe 2-3 candidate from each party.
Then one final set of primaries the last Tuesday in May that will determine the nominee.
Do you mean 50 primaries, one in each state...?
