Tough to say. It APPEARS from Ballotpedia (fwiw) that there was some kind of of judicial intervention?
At any rate, Ballotpedia lists 5 races the Democrats are targeting this year; 3 in suburban Philly, and two in the Allentown area. Of them one (Dist 26) is an open seat with a +3 D PVI. Two other districts (6 & 16) have +4 D PVIs, but also long-time GOP incumbents who won by substantial margins in 2010 (though one under 60%).
The other two races don't have their PVI mentioned, though one is a rematch from 2010 where the Democrat challenger lost by almost 30 points, and the other is an open seat around Monroe and northern Northampton counties where the Republican candidate is a long-time state rep from Monroe.
I'd like to hear Phil's take on the races, but Dems seem challenged to take the necessary second seat. No idea off hand about the State House prospects.
