CNN draws attention to Allegheny County, Pennsylvania, home to Pittsburgh.
Pittsburgh was a treasure of the industrial age, and as the times have changed, so has it. This blue pocket of the post-industrial United States sits in Allegheny County, a hub of urban and suburban life in western Pennsylvania. Far from the liberal hub of Philadelphia in the east, this county is the heart of battleground Pennsylvania.
If Hillary Clinton scores a big victory here, it’s a strong sign of her chances in this swing state. But if Trump sways this county, or turnout here is low, it could mean he takes Pennsylvania — putting him a lot closer to overall victory.
