I think the States should be divided into 5 regions of 10 states each. On ten consecutive Tuesdays, starting the first one in February, one state in each region holds a primary. The order of the states within each region is randomly chosen each primary season.

Actually, I like your idea better. But IA and NH should still go first by tradition. So that means 5 regions with 9 or 10 states in them.

Why? What makes them special? Why not Vermont and Nebraska?
