Given that even in the bluest states, the crazy is concentrated in the urban areas... I feel like we should re-think and explore the idea of the sovereign city. Draw a neat line around each urban megalopolis and its commuter suburbs, snip it loose from the rest of the state it's nested in, give it its own government, and make that government negotiate with the equally sovereign governments of the more rural territories that surround it, for water rights, unmolested transport of goods, a place to put their power plant, and a price for the inevitable groundwater plume, air pollution, and toxic runoff it produces, its landfills, its sewage output, the food grown nearby and sold in the city-- everything that must come from outside, or leave the city as waste streams. And they must be cut off from making rules that affect the whole country. The city is the city, and city rules apply nowhere outside the city.
