David Wasserman looks at the new Pennsylvania map this way: The six Democratic pick-up opportunities became even stronger pick-up opportunities when it comes to the Cook Political Report’s Partisan Voting Index. Under the old map, the six most vulnerable Republican seats were a median R+3:
- PA-6: R+2
- PA-7: R+1
- PA-8: R+2
- PA-15: R+4
- PA-16: R+5
- PA-18: R+11
Under the new map, they are even:
- PA-1: R+1
- PA-5: D+13
- PA-6: D+2
- PA-7: D+1
- PA-10: R+6
- PA-17: R+3
