Northern Kentucky River Cities

[ProgressiveModerate]

I think it's definitely culturally related to the Cinci metro. One factor is that western and southern Cinci suburbs have a high German ancestry which tends to be a very Republican contingent of whites. In general, Cinci has pretty decent racial political polarization with very few liberal white pockets and the Kentucky side is almost entirely white. Map below



I think another factor is that frankly the Kentucky side of Cincinatti is still underdeveloped relative to Cinci. This is a common theme of American cities built on rivers that also serve as borders of two states like Omaha Louisville, and Memphis - one side just becomes really dominant and the other underdeveloped by comparison even if there is close proximity to downtown.
