The Idaho panhandle where Nevada is looks bizarre. Realistically most of Nevada would be part of Utah, with the southern part (basically Clark County/Vegas area) given to Arizona. The western part might go to the northern California state. Mexico looks weird too. Why'd Nuevo Leon eat most of the southwestern parts? Why'd Sonora lose the Gadsden purchase territories?
In Canada, the Maritimes are plausible (PEI might get a free pass to statehood due to being a separate colony, otherwise it gets merged with Nova Scotia or New Brunswick, both of which would be states), Southern Ontario, Newfoundland (with Labrador, although that might be a separate territory which will never get statehood), and the southern parts of the Prairies and BC. I doubt anything else would ever have the population, except maybe the state in northern Alberta which includes the Northwest Territories. I could see Alaska and Yukon being merged (no need for that weird division). Maybe even merge it with the northern BC territory (it would still only be the 2nd or 3rd largest administrative division in the world after the Sakha Republic and Western Australia). Greenland, the northern Manitoba/Nunavut territory, and everything around Alaska would never be a state (and I can't see Alaska being a state either here unless it merged with its neighbours and/or annexed the panhandle).
