OK, nevermind. I think I figured out a better way to do NoVa. It looks cleaner this way, and also the PVIs are better. This only changes the 4 NoVa districts, and keeps everything else the same.
VA-06: D+3.8, was D+2.2 in version just above
VA-08: D+14.5, was D+18.6 in version just above
VA-10: D+2.7, was D+3.9 in version just above
VA-11: D+6.5, was D+3.9 in version just above
You can also see pretty clearly that it would be very easy to give VA-11 just a little slice of Fauqier County, and that could be used to sure up both VA-10 (and maybe VA-06 a bit also) further if it was thought that is needed at all.
This looks to me like a pretty good roadmap for Dems to draw a 9-2 map of VA. Basically smooth out the lines a bit and maybe tweak a bit with careful attention to any ways that the Clinton/Northam/Kaine numbers deviate from PVI (since that data is not in DRA), and I think you basically have pretty much the best Dem Gerrymander of VA that you can make (provided that you are not willing to fully spaghettimander NoVa or to rescue the Dems in Roanoake).
Can anyone make any improvements to this basic sort of outline?
umm... the purple district isn't contiguous, for one.
