Ohio vs Pennsylvania

[Battista Minola 1616]

I made more calculations:

Pennsylvania 2020
1.
Philadelphia MSA - Biden+33 (1/3 of state)
Rest of Pennsylvania - Trump+15 (2/3 of state)

2.
Philadelphia MSA - Biden+33 (33% of state)
Pittsburgh MSA - Trump+2 (19.5% of state)
Rest of Pennsylvania - Trump+20 (47.5% of state)

3.
Philadelphia MSA - Biden+33 (33% of state)
Pittsburgh MSA - Trump+2 (19.5% of state)
Allentown-Bethlehem MSA - Biden+1 (5.5% of state)
Harrisburg MSA - Trump+5 (4.5% of state)
Scranton-Wilkes Barre MSA - Trump+12 (4% of state)
Lancaster MSA - Trump+16 (4% of state)
York MSA - Trump+25 (3.5% of state)
Reading MSA - Trump+8 (3% of state)
Rest of Pennsylvania - Trump+31 (23% of state)

Ohio 2020
1.
Cleveland MSA - Biden+14 (18% of state)
Columbus MSA - Biden+8 (18% of state)
Rest of Ohio - Trump+19 (64% of state)

2.
Cleveland MSA - Biden+14 (18% of state)
Columbus MSA - Biden+8 (18% of state)
Cincinnati MSA - Trump+8 (15% of state)
Rest of Ohio - Trump+22 (49% of state)

3.
Cleveland MSA - Biden+14 (18% of state)
Columbus MSA - Biden+8 (18% of state)
Cincinnati MSA - Trump+8 (15% of state)
Dayton MSA - Trump+9 (7% of state)
Akron MSA - Biden+5 (6% of state)
Toledo MSA - Biden+4 (5.3% of state)
Youngstown MSA - Trump+6 (3.7% of state)
Canton MSA - Trump+21 (3.5% of state)
Rest of Ohio - Trump+42 (23.5% of state)

[both states have a pretty clear gap between the >400k metros and the <180k metros with the only exception being Erie, which I put in the "Rest" because I felt like it - if I separate it as well, Rest of Pennsylvania becomes Trump+34]

So:
Rural/micropolitan Ohio is somewhat more Republican than rural/micropolitan Pennsylvania.
Midsize metros in Ohio are actually on average somewhat more Democratic than those in Pennsylvania.
Cincy is somewhat smaller than P'burgh but also more Republican.
C'bus + Cleve combined are somewhat larger and MUCH less Democratic than Philly.

The Cleveland-Pittsburgh difference is interesting.

The main differences seem to be:

Pittsburgh is a much whiter metro than Cleveland

Pittsburgh is Appalachian, Cleveland is Great Lakes/Yankee

Cleveland probably has a less working class white population in the metro, has some "liberal elite" or Main Line-esque type suburbs like Shaker Heights and Pepper Pike that I don't think Pittsburgh really has the equivalent of.

I don't think that "latte liberals" are totally inexistent in the Pittsburgh metro. I think the main difference is TEH COAL... there is nothing like Westmoreland or Washington counties (which are not exactly tiny counties) near Cleveland.
