I'm sorry, but NO part of ANY state NORTH of the Ohio River is in any way part of "The South". Yes, there are certainly southern INFLUENCES in parts of southern Illinois, southern Indiana, and southern Ohio, but to try and assert that any part of those three states is "The South" s just plain ignorant, IMO.
Furthermore, no state that was NOT part of the original Northwest Territory of the USA (Ohio, Indiana, Michigan, Illinois, Wisconsin, and parts of Minnesota) can be considered to be in "The Midwest" or Midwestern. The Mississippi and Ohio Rivers are the diving lines there (except in northern Minnesota). So sorry Iowa, Missouri, and Kentucky (and Great Plains states like the rest of Minnesota, the Dakotas, Kansas, and Nebraska) but you're not part of our region. All or parts of those states may have quite strong "Midwestern influences", but they are NOT a part of "The Midwest".
Feel free to disagree, if you feel you must do so.
