Pittsburgh is pretty conservative culturally speaking. Very Pro-Life. Not terribly gay friendly (though they are pounding on that door really hard). Yet those same people will vote 80+% Democrat because, rightly or wrongly, they feel it is in everyone’s best economic interests.
When you say “economic” are you really saying “union” and the revolving slush fund between Big Labor and the Dems? Surely, the people of Pittsburgh aren’t stupid enough to think that the Dems actually understand economics, are they?
