Well for sure there is no way the Progs would allow the Oregon legislature to agree even if they were on board. Assuredly if this were th o seem on the verge of happening then Eastern Washington would likely seek to join as well. And Idaho as we know it would cease to exist. Though the two NY transplants I know, both of whom live in C d’A, Idaho and work at an oncology clinic in Spokane, are totally on board with this.
The progs could be rid of those pesky rural "subhumans", and be required to provide fewer services to the non-wokes.
Idaho would pick up some land east of the Snake, most of it pretty arid, but all of it attractive in a rugged sort of way.
