Yeah, I don't really know the details of each district, but I was surprised the PA House and Senate are both rated as Lean R.
With that said, if this is really a D+6-D+8 year (as some polls currently show), we could see a lot of surprises downballot.
It'll take more than a D+8 year to flip the PA Senate, of course not counting unknowable severely anomalous local hijinks. The Lancaster County seat we have to flip is about an R+13 seat, and despite Governor Wolf pulling 47.5% in Lancaster County in 2018, and the blueing of the Philly burbs spreading slowly outward to the secondary collar counties, I imagine it's too early to start expecting Democrats to flip Lancaster County.
A D+6/+8 year could give Dems control of the PA House, though.
Wouldn't be so sure about that, democrats have still a lot of House districts which are very Trumpist, they will be hard to defend and at least two of them are already pretty close to being lost (the one in Schuylkill and the one in Cambria).
