New England Yankees - as dialect and cultural scholars will tell you - settled upstate NY, the southern shores of the Great Lakes, (north PA-to-north IL), and all of Michigan/Wisconsin/Minnesota as Americans moved west. However, many of these areas are part of states where the Midland dialect/settlers from the Mid-Atlantic dominate, and in a few cases even people from Appalachia are part of the state's cultural makeup (Illinois's 'Little Egypt' and the term Hoosier originates from Indiana's Scotch-Irish south, for examples).
What if more Yankee-settled areas became their own states? To writ:
-Western New York
-North Pennsylvania/'Westmoreland' (possibly extending to Pennsylvania's western border and including Erie)
-North Ohio/the Western Reserve/'Erie' (possibly extending to Ohio's western border and including Toledo. Also, the Reserve was called 'Erie Territory' at one point before being subsumed into Ohio)
-North Illinois/'Chicagoland' (possibly including northern Indiana and including South Bend)
That said:
-What would the impact be on national politics?
-Would the southern states split themselves up more (I'm gonna assume so, so we don't have endless discussions on the free-slave split)?
-How would these areas fare on their own outside of the OTL state they're part of?
-Would they be more liberal or conservative than their real-world political affiliations?
