I’ll admit, the map is meaningless. It will have to be states sovereignly deciding to secede as free states, and can LATER form a confederation of states for a common purpose. That does not mean that they would have to form a single confederation of states. They might form 2, 3 or more, based on geographic contiguousness and political ideology.
I've had this odd idea; why not just abolish the Federal Government. Secession is messy and there is no clear process for it. A convention of the States (like Mark Levin is always talking about) could be used to pass a resolution dissolving the United States of America in its entirety.
2/3 of states to call the convention, 3/4 to pass the resolution. 2/3 of 50 is 33..3 Trump won 30 states.
3/4 of 50 is 37.5.
