Pittsburgh's in a blue state, but there are a lot of country music fans here who vote conservative, so this doesn't surprise me.
Don't kid yourself... Pennsylvania is a very red state... with a suburb of NYC stuck inside our eastern border called Philly that throws the state blue during presidential races.. but I don't think that will last for much longer.
Pittsburgh region votes redder every election... the trend will continue leaving just Allegheny County as the only blue vote total getter within a few cycles outside of the philly region.
Pittsburgh democrats are old time souther democrat types more than modern liberal gay marriage dems... Most are Dem in registration only, not remotely in their politics.. and as they die off, this part of the state will continue to redden.
