Differences aren’t entirely regional, so the solution may not be a breakup. For example, if Pennsylvania was to become its own state, Pittsburgh and Philadelphia are undoubtedly “blue” while the rest of the state is firmly conservative.
Pennsylvania as its own state does not solve the issue and it may well exacerbate it. America appears divided on a large scale, yet if one zooms in, the problem is not necessarily solved. Furthermore, diversity is a strength, not a weakness. Countries have thrived on homogeneity (i.e., Japan) – yet is this the kind of country the United States aspired to be?
Hearing different voices, balancing the needs and wants of many, that is what solidified the United States as a world leader in the first place.
