I do have a map suggestion, though after seeing Dallas' suggestion, it might be too simplified. Oh, I do realize that Piedmont would better go where New Dixie is, but I couldn't find an idea that would join up that area. Appalachia would leave out Delaware. However I COULD do "Crabcakeland", though I would have West Virginia with Heartland, though my idea was to not Gerrymander the states and keep it into one blob. Ugh Civil War and Virginia-West Virginia split
EDIT: 12 Constituencies, not including the Territories. We could split them to make it 14, just in case if there's number superstitious people here (TBH I am a bit. It's mainly just uncomfortableness, other than that its okay.) Also, after further looking, Winnebago and Rust Belt could be fused. Both Dixie's and Heartland as well. Deseret, Big Sky, and Great Plains could be made into one big megastate, though we would run into one of the biggest problems that plagued Atlasia, the megastate problem.
