I can say for sure none of it’s very Northwestern; even eastern Washington is more like Idaho than the coast.
Rockies is fair, for the part that they actually run through, which seems to be more like a third of the area and inevitably less populated. I guess that’s the part they like to advertise, though, and clearly it has worked.
I’ve never seen or heard Montana called Midwest. It’s more Rockies or Northwest. Eastern half could be considered Great Plains-ish.
