Pennsylvania has taken up Ohio's mantle as the national bellwether. As Sol said, it has "a little bit of everything" in such a way that it will likely remain swingy in almost any political alignment. It's basically Vigo County, Indiana scaled up to the size of a state.
I like the VA+WV comparison. Perhaps it could be done for some other states too. IL + IN = MN?
This kinda makes sense, Ohio and Pennsylvania are actually really similar just Ohio’s more to the right of the nation. Both have massive growths in their capital along with some suburbs with a slow decline in the manufacturing and rural areas
