I mean yeah, if Biden is the nominee Trump has zero chance in Pennsylvania. He will still win at least 40% of the vote which accounts for millions of people.These stories always focus on hold-outs. Generally best to ignore them because they're selection bias for the eyes.
This is like finding those random Pennsylvania workers still eager to support Trump. He has no hope in PA anymore. I say this as a local who is watching the dynamics shift in the state rapidly.
You're right that media focuses too much on the holdouts. Voters do too, I've seen the "x% of Americans believe y, are you saying they're all stupid/bigoted?" argument from South Park repeated verbatim, unironically plenty of times.
