I've said this time and time again, there are no "Steel States". PA is not a steel producer anymore. Steel Unions still exist here, but, politically, they are getting as rusty as the factories that haven't been used in 30 years. PA is begining to evolve beyond steel and this election will reflect that.
Ah... but SW Pennsylvania was built on Steel and I'd guess it'll still have a big emotional pull.
Heavy Industry does that kind of thing a lot... examples: no Coal has been mined in Wigan for a long time... but it's still a coal town. No Steel has been made in Ebbw Vale for over 30 years... but it's still a steel town.
Strange things people.
BTW there still is a steel industry in WV
