I think Eastern Washington and maybe parts of Northern California want in on this..
Not sure if Idaho is interested
Idaho had damned well BETTER be interested; leftist transplants and the university have about turned Boise and environs blue. As far back as 2005 you already had the once farm-edge burg of Eagle billing itself as “The Napa Valley of Idaho” do you can be sure the parasites are well entrenched by now in HOA’s, PTA’s, City Councils, and busybody civic roles of every description.
Rural Idaho won’t have offsetting numbers much longer without this annexation from more westerly States.
A few years ago. there was a movement to join parts of Washington, Idaho, and Montana into "Idawasmont."
