I was reacting to the map, which showed Kentucky colored as Midwestern. The definitions in #89 leave out Kentucky.
I noticed that too. The entire Wikipedia entry for midwest doesn't mention Kentucky. Although they do discuss Virginia's claims to the Northern Ordinance "Old Northwest" territory. One might presume that claim to include the current states of West Virginia and Kentucky.
Midwestern influence is felt in Pittsburgh (an old pioneer town), West Virginia (which seceded from Virginia), Louisville (an industrial city on the Ohio River) and, with some irony, in former states where slavery was legal or tolerated before the Civil War, including Missouri, Kansas, Oklahoma, and parts of Texas, Arkansas, Tennessee, and Kentucky, though most of these cities and states are not truly Midwestern.It's about 2/3rds of the way down the Wikipedia page under the section on "Culture."
