I'm skeptical that Maryland Democrats will go for 8-0, but if they do, this is the way to go.
MD-1: Andy Harris
50% Obama, 47% McCain. Avg. 52% Dem, 47% Rep.
Drops some of the heavily GOP Eastern Shore and picks up parts of Prince Georges and Montgomery. At R+1, it's winnable for Kratovil if he wants to come back, but still marginal in a wave. Harris is in MD-2 on this map, but he'd run here.
MD-2: Dutch Ruppersberger.
56% Obama, 41% McCain. Avg. 60% Dem, 39% Rep.
Ruppersberger is slightly reduced, but otherwise fine. Tried to make sure his hometown stayed in this seat, which was hard, since Sarbanes resides in a nearby town, but I think I've kept them both in their districts.
MD-3: John Sarbanes
56% Obama, 41% McCain. Avg. 58% Dem, 41% Rep.
Sarbanes also takes a reduction, but is otherwise fine.
MD-4: Donna Edwards
85% Obama, 13% McCain. Avg. 84% Dem, 15% Rep. 51% Black.
Kept it VRA secure and still managed to spare some Democrats to MD-1.
MD-5: Steny Hoyer
59% Obama, 39% McCain. Avg. 60% Dem, 39% Rep.
Hoyer is the next Democrat to take a reduction in order to boost MD-1's number of Democrats. Hoyer would be fine here and being Minority Whip and formerly Majority Leader, he probably doesn't mind taking a some reduction to boost Democratic chances.
MD-6: Roscoe Bartlett
52% Obama, 45% McCain. Avg. 52% Dem, 48% Rep.
Bartlett goes from a heavily McCain district, to an almost even one. The smart thing about it is that most of the Republicans are very conservative, so a moderate Republican who could potentially win would not get out of the primary.
MD-7: Elijah Cummings
76% Obama, 21% McCain. Avg. 76% Dem, 23% Rep. 51% Black.
Cummings takes on some heavily GOP precincts in Anne Arundel County, so Sarbanes and Ruppersberger don't have to.
MD-8: Chris Van Hollen
61% Obama, 37% McCain. Avg. 62% Dem, 37% Rep.
Van Hollen takes a big reduction in order to take in very conservative counties in the panhandle. He'll be fine here and his seat being unpacked helps create another winnable district.
