Could that ever happen? Is it a real path.
If the best (or worst, depending on your perspective) case scenario in that map doesn’t leave much left of Oregon. Seems like the rest of Oregon should get annexed into Washington, since (perhaps) their politics are more amicable with each other. The lefties would never want to lose the 2 seats in the Senate though.
Eastern WA might want to join eastern OR in Idaho. I doubt anyone is going anywhere.
Ignore the demons in Portland and DC and petition the Idaho legislature to vote on it.
Onto your topic, that map is not good. Southern Oregon should not be anywhere near idaho. We don’t want more leftists to domicile in Idaho. Defeats the purpose of the eastern counties leaving.
We can’t continue on this path, if we have any hope of keeping this geographic entity together. I see three options:
1. No change state borders. Most likely and you can kiss the US good bye.
2. Change borders, keeping number of states the same, Less likely.; but doable.
3. Combine states, I.e. De and Pa, reducing number of states to more manageable levels. Highly unlikely: nobody is going to want to give up power.
Or maybe even get rid of some entities altogether, give CA, NM and AZ back to Mexico. Make Hawaii and Alaska independent, with defense treaties..
