There actually isn't a whole lot new to talk about gerrymandering wise if that's the apportionment. R's are most at risk to get wiped out in NY, CO and NV and D's are most at risk in AZ and IL. Court maps would improve D prospects drastically in OH, MI, PA or VA. If D's somehow take control in OH or PA, expect nuclear war on a map (10 districts into Philly or Cuyahoga).
Democrats drew the Illionois legislature to make sure that they have two thirds majorities in both Houses pretty much all of the time, meaning they will be able to override a veto. And figure in the fact that the governorships of OH, MI, and PA usually switch parties every eight years and will be open in 2018, leaving Democrats in great shape to pick those up. Getting court drawn maps in those three states alone would probably cost Republicans 10-12 seats right there.
