That would be an epic win. We will take the eastern part of the state. Oregon and WA state should join them.
The Willamette Valley of Oregon (Portland south to Eugene) is the part of the state that is socialistic. The rest of the state is rural and conservative.
In Washington, it's the part west of the Cascades that is socialistic. East of the mountains, it's rural and conservative.
Washington is actually two states unhappily married at the Cascades, and the same is mostly true for Oregon.
If the US is divisible, then California is divisible. If Washington and Oregon wish to leave, then both states are divisible. Western Washington would probably be happier annexed into the Canadian province of British Columbia.
