Wisconsin was a compromise map, the legislature was split.
Georgia's current map is a Republican gerrymander enacted in 2005.
North Carolina's current map is a Dem gerrymander, as far as I know.
Mass and Maryland wouldn't matter -- the Democrats have veto-proof majorities.
Wisconsin actually looks like a fair map, aside form the First district (which was drawn to keep Paul Ryan in it), the map's decent.
Georgia is currently a Court-drawn map IIRC. Republicans tried to re-gerrymander it in 2003 after the Democrats did in 2001, but it got struck down by the courts.
North Carolina is most certainly a Democratic gerrymander--its' the best possible map for them
Mass and Maryland unfortunately won't matter at all, given that Dems hold something like 80% of the seats in the former and large majorities in the latter.
