South Carolina and Georgia aren't going to accommodate Democrats. This looks to me more like a gesture of good will towards Clyburn and black voters by Biden.
I think the final solution will be having Nevada and New Hampshire primaries taking place on the same day.
I think it may have changed to a state run primary last cycle but for years the South Carolina presidential primaries were party run, if they have to have a party run primary again in 2024 I'm sure they will. What the final lineup will end up being.
1) New Hampshire- They have the flexibility and the will to move up as far as they need to to be first. Big question is how severe the DNC sanctions will be.
2) South Carolina
3) Nevada
4) Georgia? I don't think this one is written in ink yet. I doubt GA Dems get any cooperation from GA Republicans. Possible party run primary but that is a question mark.
5) Michigan.
