1 (blue - South Philadelphia): 87% Obama. 53% black. Safe D.
2 (green - Philadelphia): 89% Obama. 55% black. Safe D.
3 (purple - Erie): 54% Obama. Given that this is in the more ancestrally Democratic half of Pennsylvania, Likely D.
4 (red - West Pittsburgh suburbs): 52% McCain. Tricky to say. It's probably too far removed for Jason Altmire to comeback here (if it isn't, then it's a Tossup and probably titling D), and the trends here probably make it hard for us to win. Tilts R, I guess.
5 (gold - Mid-Northern T): 51% McCain. Amazed it was this marginal. Did Chris Carney represent much of this area in the old PA-10? If so, Toss-up. Probably Lean/Likely R otherwise.
6 (dark green - Berks): 54% Obama. Jim Gerlach's stomping ground. He'd still hold the seat now, but given he's retiring it's Tilts D going forward.
7 (grey - Chester City/Delaware County): 63% Obama. Safe D even taking into account how moderate Philly Republicans are.
8 (violet (?) - Bucks): 51% Obama. Likely R for Fitzpatrick, Tossup if Open.
9 (teal - South Western T): 63% McCain. A whopping 97%
white. Safe R.
10 (pink - NE Pennsylvania): 58% McCain. Safe R.
11 (lime green - Scranton/Wilkes-Barre): 60% Obama. Safe D.
12 (some lightish blue - SWPA/coal country): 52% McCain. Arguably the most fertile ground for a Blue Dog/pro-coal Dem, Gore probably won here and Kerry might have too (so Obama was a uniquely bad fit for here). It is trending right pretty hard though, so Tossup.
13 (Montgomery): 58% Obama. Would ordinarily be safe, but might be close in 2010 like circumstances. Likely D.
14 (khaki - Pittsburgh): 73% Obama. Safe D.
15 (orange): 52% Obama. Tossup normally, but I guess Charlie Dent runs here, in which case it's Likely R for him.
16 (light green - Amish Country): 59% McCain. Safe R.
17 (dark purple - Harrisburg): 50% McCain, he won by about 2,000 votes. Probably Likely R in neutral circumstances, but the district seems a really good fit for Tim Holden, so the district would probably lean in his favour if he does come back.
18 (yellow - Westmoreland): 59% McCain. This part of SWPA probably wouldn't vote for a Blue Dog these days. Safe R, particularly if Tim Murphy runs here.
19 (Philadelphia): 85% Obama. 41% white (but still plurality white). Safe D.
20 (North Philadelphia): 60% Obama. The most white and least Democratic seat in Pittsburgh proper. Safe D, might be close in a wave I guess but even then....
21 (maroon): 57% Obama. Lean/Likely D, but Pat Meehan would probably prefer here than the 7th. He would make it close, but even with him it probably would still Tilt D.
22 (dark brown - Chester County/Lancaster): 54% Obama. Tossup given what sort of candidate each side would run in Philly suburbia.
23 (pale blue - Lehigh Valley): 57% Obama. Probably Likely D given that I doubt Dent runs here when he's got a more viable seat available in the shape of the 15th.
24 (very dark purple): 56% McCain. Safe R.
25 (East Pittsburgh suburbs/Penn Hills): 54% Obama. Close-ish on paper, but any Obama district in this part of the country is Safe D.
26 (North Pittsburgh suburbs): 55% McCain. Would be Safe R generally, but this district is similar to Jason Altmire's old district, so for him it could well be a Tossup.
27 (pale-ish green): 56% McCain. Safe R. Like the 9th it is 97% white.
28 (South Eastern T/York): 58% McCain. Safe R.
Safe D: 8
Likely D: 3
Lean/Likely D: 1*
Tilt D: 1*
Tilt R: 1*
Lean/Likely R: 1*
Likely R: 1*
Safe R: 8*
Again, my footnote for North Carolina applies for Pennsylvania.
