It's not so much of a "flyover" state dynamic -- it's more rural vs urban.

States like OH and KY have more rural space, which tends to lean conservative, which increases the chances of hearing about extreme-right nonsense.

I would imagine the opposite is true in states with more urban space and the nonsense of the extreme left.

Urban areas in OH and KY are similar in terms of cultural offerings and advanced technology of most cities. Or at least they are in Columbus....
