I mean, Maryland is gerrymandered for reasons other than partisan reasons. Most of the messiness is to create two separate districts for white Democrats from Baltimore and its suburbs (the real problem) and otherwise preserve incumbents in their districts. It's possible to draw a much neater map that is nonetheless solidly 7-1.
You can actually draw a relatively neat 8-0 map. It doesn't even split the Eastern Shore that bad and it uses the Bay Bridge to cross over into Prince George's County.
Amazing how a gerrymander can look better than what exists now (presumably also gerrymander).
