I didn't follow the whole issue. However, PA should still be interesting given (1) a possible (I said possible) increase in black support for Trump, and (2) the steel tariffs and coal production coming back. Will blacks come out for Repubs? Will union members vote for them? Who knows.
As far as my prediction for the House, Dems +20. Senate, Reps + 4 (making Murkowski's future votes much less important).
