It's Bama. Found the original quote on Wikipedia:
"Between Paoli and Penn Hills, Pennsylvania is Alabama without the blacks. They didn't film The Deer Hunter there for nothing – the state has the second-highest concentration of NRA members, behind Texas."
For North Alabama, that's dead-on. If you got kidnapped by a PA/AL cartel and dumped in the woods of either state in your underwear you'd be hard-pressed to tell where you were until you tried to buy beer in a gas station. Beer = Bama. No Beer but it's a Sheetz or a Wawa = Penna.
(Let me get this tweed jacket on and light this pipe) Beyond that, Carville actually got it backwards. It's Alabama that's Pennsylvania minus Philly and Pennsylvania Dutch. When central PA was first settled it was heavy with Irish types who had 8 kids, and some went west, some stayed home, and the rest piled down along the Appalachian ridges through all those states and the last one was Bama. (There's hill in Mississippi that they sometimes claim as the end of the Appalachians-- they lie.)
