I’d let all the liberal states leave, and let the purple states with a definite red and blue area (like FL, CA, and WA) split.
It’d be easy and somewhat natural to say Aloha (which ESPN taught us means goodbye) to Hawaii. Not connected to the 48 states, just an island (well actually a collection of islands) like Puerto Rico or American Samoa.
Put Hawaii on eBay and remove its star.........Hmmmmmm, Californication too?
