Washington and Eastern Washington is well known and documented, North Idaho has a similar dynamic in which its residents often feel disconnected from the state's political center in Boise. The Idaho Panhandle is most often considered to be the ten northernmost counties in the state—Boundary, Bonner, Benewah, Clearwater, Idaho, Kootenai, Latah, Lewis, Nez Perce, and Shoshone. These counties are separated from Southern Idaho by the Salmon River and observe Pacific Time, unlike the rest of the state, which uses Mountain Time. Parallel suggestions of a "State of Kootenai" have been made, referring to a proposed union of the six northernmost counties of Idaho, and the six westernmost counties of Montana, creating a geographically, politically, and ecologically connected state of 524,888 residents, putting it ahead of other states such as Wyoming. Eastern Washington and eastern Oregon Other conceptions of a potential "State of Lincoln" have been rendered, specifically a possible combination of eastern Washington and eastern Oregon. The people of Eastern Oregon also often express the same frustration with being coupled with Portland and the region west of the Cascades that Eastern Washingtonians do with respect to Seattle. This proposed coupling would create one of the largest states by area in the country, stretching all the way from the eastern foothills of the Cascade Mountain Range to the border with Idaho in the east. Proposals The state legislatures for Idaho and Washington have seen bills proposing secession or splintering. Idaho would not go along as at the time the Panhandle generated more tax revenue per capita than the south. If combined with the proposed State of Jefferson, which overlaps a proposed Oregon-Washington "State of Lincoln" in southeastern Oregon and is proposed for many of the same reasons, it would create a state that is even larger. The Inland Northwest region roughly corresponds to the area that might comprise such a State of Lincoln. The largest city would be Spokane, Washington, which is presently Washington's second largest and the greater Spokane area is the third largest population base in the northwestern US behind Seattle and Portland. A Spokane proposal in 1907 called for a new state "Lincoln" to be created from eastern Washington, northeastern Oregon, and northern Idaho. Oregon and Washington's eastern boundary would have been shifted westward to 120° W, aligning with California's eastern boundary. Idaho's northern boundary would have been shifted southward to 45° N, aligning with Wyoming's northern boundary.
