There’s a novel entitled THE PEOPLE’S REPUBLIC based on the leftists exiting the U.S. Fun book.
If any state wants to go, there the matter of lingering debt obligations to be cleared. The most equitable distribution would be by HoR representation. California has 53 out of 435 House members, or about 12%. So California’s percentage of the outstanding federal debt is 12% of $21 trillion. So about $2.5 trillion is their liquidated buyout. But there are billions of dollars in public land as well as military installations, the value of which will have to be rendered in the split. In fairness there’s billions sitting in SS accounts that will need to be returned as well. They should do it soon, so we can correctly locate the western boundary of the border wall.
