Sadly, the entire Pacific coast is going to have to be eventually "written off" from America, if the central core of the country wants to survive -as- "America".
Perhaps the same for the New England states.
No nation lasts forever.
Borders change.
Populations change (as ours is "changing" now).
Governments change.
Perhaps the old "Ann Landers question" should be considered:
Would "traditional America" be better off with the west coastal states -- or WITHOUT them...?
