Your posts always are so pretty. I believe any shift would require the approval of Idaho, Oregon, and Congress. I could be wrong though.
Oregon might actually support it. What does Idaho think? Has anyone asked the potatoes? Won't someone think of the potatoes?!!
Both state legislatures would have to approve, then it would go to the US Congress.
Idaho would almost certainly be in favor of it, the Oregon legislature now always heavily dominated by Dimocrats, would of course vote no.
