a little idea i've been bouncing around for a while is basically that, instead of being formed along full-on states, OTL's USA instead becomes a collection of numerous city-states (and satellite cities and rural regions of said city-states; the smaller cities in a city-state could be called burroughs if you want). what does everyone think the political geography of the UCA/UCsA would look like in such a situation, as well as what politics would look like. for a starting point, the established megaregions of the OTL US could be included. this would also mean that some city-states are exponentially larger than others while some city-states are so small and so far out of the way that they'd be as obscure to Americans in general as (geographically) small countries IOTL like Brunei, Malta, and Lichtenstein
also, i'd be willing to hear ideas for how elections could work in a UCA setting like this; currently, the only thing that comes to mind is that electoral votes are limited to one per city-state regardless of how large or small they are, but otherwise function the same
also, there could/would probably be more successful--but less-impactful [sic]--secessionist movements, both on the state level and on the federal level. suppose that a city-state in this scenario has satellite cities which are further away from the main part of the city-state (let's say Las Vegas to Los Angeles, just to use OTL cities): Vegas starts out as a stopover between the east and west coasts (assuming that a UCA would grow that large) but eventually becomes so large a place and so disconnected from Angeles that it splits and becomes its own federally-recognized city-state. this could also lead to some interesting situations concerning the issue of slavery, where some states more disconnected from the South join the ACW (again, assuming that such an event even comes to pass) while some parts of the OTL South that didn't agree with their rebellion choose to stay in the Union
