At this point I am for secession. The downside though is the West Coast and the Northeast become a Chinese colony. So what about the Monroe Doctrine? The last time it was really implemented was during the Cuban Missile Crisis.
Maybe parts of California and Oregon could become the State of Jefferson (as was proposed in the past), and much of Southern California could be ceeded to Mexico. That way the free states of the new U.S.A. would have access to the Pacific.
Maybe some of the big Blue cities in Red states could become independent city states. They would quickly collapse once they are supposed to be self-supporting. I guess if they want communism and starve as a result, then that is their problem. They can ask Venezuela for oil and food.
