I don't expect fair maps, persay, just ones that aren't hideously gerrymandered like Ohio this year or Maryland or Massachusetts last time around. I think we ought to be drawing Indiana/Wisconsin type maps that do favor the party who drew them but aren't ridiculous. As for Illinois, I'd like to have seen something a little more even-handed, but it wasn't truly awful.
As ugly as Massachusetts is, it's obviously not for partisan gain. You'd get the same result on a fair map.
Half the districts in the state seem to find their way into Boston so it's not exactly a fair map. Still, you're likely right that Massachusetts would have a straight-Dem delegation regardless, but they have effectively removed the potential for contested elections. They might otherwise have to spend money or actually campaign in some seats.
