Everyone seems to like 2, 4, and 6.
Let me break that down a little bit here:
Each map has three (3) regions. Basically: west, north/northeast, and south/southeast.
States which are in each region in all 3 maps:
West: Current Pacific, Montana, Wyoming, Colorado, North Dakota, South Dakota, Nebraska, and Kansas.
North: Current Northeast (minus Delaware), Ohio, Indiana, Wisconsin, Illinois, and Michigan.
South: Current South, Virginia, Missouri, Kentucky, Oklahoma, and West Virginia.
Now, as far as substantive differences are concerned, these 3 maps have different fates for Minnesota-Iowa (grouped together) and Maryland-Delaware-DC (also grouped together).
Map 2: MN-IA and MD-DE-DC both in the North.
Map 4: MN-IA in the West and MD-DE-DC in the South.
Map 6: MN-IA in the North and MD-DE-DC in the South.
Honestly, I'd go with an alternate that has the other combo: MN-IA in the West and MD-DE-DC in the North. Why would we move Delaware, currently in the Northeast, to the South? And if we put MN-IA in the West instead of the North, it keeps the entire Midwest region intact except Oklahoma--although merged with the Pacific.
When making these maps, it's important to consider the current borders and not change things too drastically. I understand the cries for radical change, and I often agree with those cries, but when drastic change works, it's when it's objectively better than before. Sending the new regions into chaos because of a map that slices old regions with no regard to past boundaries will not help anything.
Something like this would work, I think:
The Leinad Plan:An alternate would be to move Oklahoma to the west, which would thus make it where the Mideast is the only region not staying in tact, although even then it will retain most of it's core. Even without that, this map makes sense, and is only very slightly different to the 3 consensus maps.
To me, this is the best of both worlds of map 2 and map 4. I suppose it's rather late, but again, it's only slightly different to some maps already proposed.
