IMO, Pa is leaning more Trump than hillary and if anecdotal information means ANYTHING ... NO ONE sees hillary signs (I've seen one and have heard of about 5 or 6), but trump signs are EVERYWHERE by the hundreds approaching thousands here in SW Pa.
Pittsburgh UST'A BE a dem stronghold, but people I know that live and work there tell of more pro Trump discussions than hillary.
Now granted, the hillary's might be "in the closet' (so to speak), but the Trump's are out front and out spoken.
That leaves only Filthydelphia which I'm TOLD is tolerable towards Trump, but no one is calling Filthy FOR Trump.
It has been traditionally Filthydelphia and Allegheny Cy (Pittsburgh) that has always swayed a red state blue.
It is not southwest Pennsylvania that will deliver the state to Clinton, it's southeast Pennsylvania. Democrats take Pittsburg, Philadelphia, and the Philly counties by such large margins that the rest of the state comes along as part of the spoils. This election probably won't be any different.
I hope so. If he wins PA then this election will be over by 6:30pm election night.
