Yeah, thats a great example of where you run into the differences between 'Cascadia' as a bioregion, defined primarily by watershed networks, snd 'Cascadia' as a maybe possible legal/political entity, based on current existing borders.
IIRC, the bioregion Cascadia basically only extends down to bits of Northern California... but the political reality doesn't match well with this at all.
Perhaps state delegates could all send couriers to Goodsprings for a conference, to hash out the details, lol.
Cascadia vs Greater California vs ... New Zion/Deseret?
