PA is full of libs, city libs and union libs.
My M I L is on that track but is in central (literally) PA, rural and small town yet I have not met a conservative there yet.
The more states oxidize in the rust belt, the more you see motivated people leave looking for greener pastures. What is left behind often leans left. The only corrections come when the census pulls seats and electoral votes from dying states.
PA is NOT full of libs. The cities are which number two, maybe three in the STATE. The rest of PA is very conservative beyond the old folks who think they are voting for democrats of old. PA has the second oldest elderly count second to Florida. Hate to say it, when the old die off is when PA becomes different/better. It will be another couple decades though; maybe the state can keep up those pension payments; we’ll see.
