It is a confusing article, but unless a black VAP majority district can be drawn connecting clear communities of interest, and the GOP map does not, and goes farther afield, I don't really see a problem with the GOP map myself. The SCOTUS decisions are hardly consistent in any event, and it continually tacks from one map review to the next. I assume that if the DOJ intervenes here, the matter will be going to SCOTUS, and Justice Kennedy will get to elaborate on, and revise and extend, his Bonilla decision.
Basically. I don't see what adding Durham instead of Raleigh Blacks will accomplish for the Democrats, either. So the White Dem pack seat moves a little further east. *Shrug* Maybe you could fight some of the coastal rural counties dropped back in, and that upsets the delicate math in eastern NC somewhat, but this article raises no issues that would affect the basic outline of the plan there (much the same is true if the Lumbee vote is held to be illegally diluted, which probably won't happen either).
As to the 12th, pish tosh. If its last version passed the Supremes, the new one will too. And if the decisions about the second-to-last one are explicitly reversed in letter, that would just clear up redistricting case law a little.
