They look to be largely based on physical geography - Blue Ridge, for example, and Mesabi after the Mesabi Range.
The disadvantages seem a little optimistic: I don't think the good people of Hawai'i would take a liking to being in the same state as Portland, OR. As a post-apoc map, I'd separate Hawai'i into its own nationstate, or even the individual islands. But otherwise, it would make for a rad Cosmic Era map, circa-22nd century.
