It will be interesting to see where this line of cases ends up. They seem to suggest that a Dem partisan gerrymander is ok because there's no standard to determine how much gerrymandering is too much. However a Pub gerrymander may not be ok since in many states there is a disparate effect of racial and ethnic minorities which vote consistently Dem. Pub gerrymanders that pack Dems cannot avoid packing minorities, but the reverse is not true. If carried to the extreme it will create an asymmetrical view of the parties by the courts, which would be a marked departure from the cases of the 1990's.
The thing is the Republican's nature works against racial minorities because ~90% of their voters are non-hispanic white. The Democrats encourage representation of minorities because so many of their supporters are non-white comparatively. It's a case of the law just being on the Democrat's side, like it or not.
You're basically asking the courts to ignore this fact and just assume each party has no relation to race. That's blatantly not the case.
