The Greater Idaho movement proposes that eastern Oregon counties become part of Idaho instead.
While the issue has seemingly divided [Wallowa County], with 1,752 residents voting in favor of the measure and 1,744 residents voting against it, McCaw said that “Greater Idaho” measures spreading across Eastern Oregon are currently more about conservative voters being heard in the Democrat-run state of Oregon than focusing on how the region would actually become part of Idaho. Despite the majority of support currently shown by voters in 12 counties around rural Oregon, it remains unclear how the proposed “Greater Idaho” border change would actually occur.
“It’s designed to allow people to have their voices heard on this and let elected officials know they want their voices heard,” McCaw said. “State legislature will decide where the border goes. [The measure] gives Eastern Oregon a voice and chance to say: ‘Here is what we want our elected leaders to do.’”

"The measure passed the state House last month and advanced to the state Senate, where it sits in committee, with the session expected to wrap by the end of March."

"Moving the Idaho-Oregon border would require the approval of both state legislatures as well as the U.S. Congress. Despite the support of Idaho lawmakers, the idea may face greater resistance in the Democrat-controlled Oregon legislature. Oregon state Sen. Dennis Linthicum, a Republican, has filed a similar proposal to begin talks with Idaho, but the proposal is unlikely to make it out of committee.
Still, proponents of Greater Idaho note that 11 counties in eastern Oregon have voted for ballot measures to explore the move and that, according to some polling, Idahoans would welcome expanding the state boundary. In Oregon, meanwhile, polling has shown a roughly equal number of voters support and oppose the idea, with about one-fifth of the population undecided."
