That’s actually an interesting thought. I think Virginia goes with DC just because they’re so intertwined. The Canadian oil fields could use developing and with the sixth largest economy in the world (California) and the New York financial powerhouse it probably happens. That lure along with proximity probably brings a few states like Wyoming, Montana, Idaho, North Dakota and Alaska. Not sure Mexico would be able to resist the opportunity to finally take Texas back.
Most of the other states...well, who cares really?
