The Economist
thinks so based on oral arguments in the Maryland case. It seems that SCOTUS is getting cold feet applying applying magic (and flawed) mathematical formulas like the efficiency gap metric, and so is still left with the conundrum as to just what to do about it all, without every single map ending up in court because the metrics are so murky. Just why they have not thought more about listing the factors: chops (including the design of the chops), erosity and so forth, and merely state that the burden of proof is on the map drawer where those metrics are not followed to prove that it was not done for partisan reasons, but rather were based on appropriate and non partisan redistricting principles, escapes me.
Breyer seems to want to delay it all, so the court can ponder it some more next term (will Justice Kennedy still be there The Economist muses). Muon2 should send SCOTUS an amicus brief, with the essentials of his metrics (chops, road cuts, respect for keeping metro areas in tact), leaving out the more esoteric stuff, but I digress.
