We can do process of elimination to find the "ideal" states:
1. Eliminate states that are geographically unrealistic
2. Eliminate states Democrats are basically irrelevant in
3. Eliminate DC because that would be stupid
4. Eliminate states that are probably too red
5. Eliminate states with no big city
6. Eliminate states with too much corruption/machine politics
7. Eliminate states that are too big (>15 EV)
8. Eliminate states that are too white (>70% white)
9. Eliminate states that aren't black enough (<10% black)
That leaves us with Nevada, Maryland, Connecticut and Virginia, the latter two being demographic compromises, but also reflecting the worst of the Democratic Party. Iowa and New Hampshire look pretty good in comparison...
