Sniffit does have it right. But in PA it’s more than the “Appalachian” parts. Up and down the I-80 & 81 corridors, outer ring suburbs of Philly and Pittsburgh, Lehigh Valley, more and more a commuter suburb of NYC _and new _ refugees - all Trump targets. For all the bullshit reasons they hear telling (white) folks they should live in fear, especially when Those People are seen as gaining power and influence. And look at the gerrymanders custom designed to create zones of white folk who will buy into the fear mongering -great for votes and fundraising.
