Why is Ohio more republican then Pennsylvania?

This doesn't answer the OP's question, but it's fascinating how the Pittsburgh metro has trended so much to the right.  Trump carried the Pittsburgh metro (as shown by the data in the above post) + solidly Republican rural Pennsylvania, yet he only barely carried the state, since the Philly metro is so large and now overwhelmingly Democratic.

Contrast 2016 with 1988, when Pittsburgh was one of the most Democratic major metropolitan areas in the country.  Bush crushed Dukakis in suburbs everywhere, but Dukakis won almost every county in the Pittsburgh area (all except Butler I believe).  Yet, Bush carried Pennsylvania by a slightly larger margin than Trump, since the Philly suburbs were still quite Republican at the time.

^ I feel by pointing out that Ohio's suburbs are, in fact, more Republican than Pennsylvania's, I somewhat answered the OP's question.

Huh?  Yes.  I said my post didn't answer it.
