Is this going to put the State House and Senate in play?
The Senate is already in play. I don't know enough about the nuances of the House to say for certain on that.
There are 19 seats separating the Democrats and Republican in the Pennsylvania State House, so it's in play, and the Republicans are going to lose quite a few seats - but I don't think it'll be enough to have the Democrats win the majority.
It all depends, though, and the Democrats just need 4 seats to pick up the Senate - which they'll meet and surpass.
That seems a bit optimistic. From what I've seen, the Senate looks to be tilt/lean R and the House looks to be likely/safeish R
