Frankly I think it's absurd that tiny little all white states like Iowa New Hampshire have so much sway and pull as to try to swing the overall primary.

Michigan changed our primary date to conform to the new DNC calendar and republicans. Are the ones here complaining that they may lose delegates if they change their date

A better idea might be to do regional super Tuesdays with a primary in all of New England and then later a primary in the Southeast and then later a primary in the midwest et cetera.
