How shameful of the Dems not to draw that district.
It's not really any worse than Central Maryland (although that is due to keeping incumbents apart, not the overall partisan lean) or Southeast Pennsylvania. Or the 2001 Dem Georgia map.
Of course, that's only because it's not technically possible to get worse than that.
As to the silly debate over what number of seats a party "deserves" under fptp... if fptp is to have any legitimacy at all it derives from its ability to elect Representatives for specific communities. It follows there is no single "fair" outcome (and the article's premise is hogwash), and Massachusetts and Maryland are excellent examples to show that. Maryland voted slightly more Democratic than Massachusetts, yet a community-oriented Massachusetts map comes out 8-0-1 or 7-0-2 - and they tilt Democratic, really - while in Maryland you get something like 4-2-2 or even 4-3-1 (D-R-swingy) because the votes are distributed much more unevenly.
