I’m in favor of it! The US will have a sea of Red surounding islands of blue cities. Red will control the food production, energy production, water, gas and everything else that is shipped to a blue city.
Wall them in and listen to them squeal like a bunch of rats as they devour each other!
If so, then Red better make it a point to get California, which can and has fed a whole helluva lot of the U.S. not just in crops, but in commercial fishing.
