On Tuesday, voters in Crook County passed measure 7-86, which asked voters if they support negotiations to move the Oregon/Idaho border to include Crook County in Idaho. The measure is passing with 53% of the vote, and makes Crook County the 13th county in eastern Oregon to pass a Greater Idaho measure.
A state isn’t being formed: they’re just moving the lines. So I don’t think that comes into play.
They’re not, though. Not without the permission of the Oregon state government, the Idaho state government, and the US congress. That’s the point. This is a tiny portion of the population of Oregon. They don’t get to just decide they live in Idaho now.
