The requirements for state ballot initiatives are clearly stated in the Oregon constitution, and the Greater Idaho movement hasn't come close to fulfilling them. Not sure why people keep throwing the term referendum around.
The state legislature also hasn't stopped the counties in question from holding biannual meetings on the issue, which is what the counties actually voted to require. Exactly what the county commissions are supposed to do in these meetings is unclear even to the county commissioners.
It might be worth asking if movements like this are why the GOP has steadily lost its majority since controlling both houses of the Oregon legislature quite recently.
