I don't see this changing much tbh.
I wonder if Massachusetts is split to keep the balance of free states and slave states... Only Western MA is the location of the new state, not Maine.One obvious consequence is that there will be two fewer free states in the Union. This would change the dynamics of the free/slave controversies, but I don't know how.
Actually I suspect a bigger difference, since west of Michigan the border would probably be somewhere between 42 and 45 N, most of OTL Wisconsin and Minnesota are likely also British/Canadian.
Be what? Realistic? So much the same in terms of bordering?they look need and orderly like that but I don't think it would be
The Red River flows deep into Minnesota and North Dakota, though. It got cut off at the 49th OTL, but it's still fairly long. The Columbia river makes sense though, especially if you adjoin "Washington" to British Columbia. Though Oregon Country was contested fiercely by both sides.I think its a hard call maybe otl plus the red river valley and the Columbia River border
How much of Michigan? One needs to remember that the UP did entirely go to the Territory of Michigan initially. In fact some of the Statehood proposals specifically rejected it. Say Canada via Britian winds up with the Lower Peninsula. Wisconsin's* analog ITTL winds up with the UP. ITTL The Union is short probably some regiments but not the 40+ Michigan raised. But they still get the oriinal 90% of Uniom copper production in the 1860s. Plus the iron ore. Plus the bonus gold and silver that came out of the iron mines. The iron and copper that came out of the UP were worth more than the gold out of California. ITTL Wisconsin also gets the NE corner of Minnesota. Iowa extends another 100+ miles north. Iowa and Wisconsin wind up with a lot of the settlers that go to Michigan. The automotive industry long with associated rubber, machine tools, glass, steel, tool & die shops, parts suppliers, etc get centered on an arc between Michigan City, Indiana and Green Bay.
