MD is gerrymandered but I think rational people can agree that the Republicans have abused the trick much more and more often than Democrats.
The census is coming up and new districts will be drawn based on census numbers. That is why Trump and Republicans wanted the "citizenship" question on there, so that minorities would be less likely to respond, thus under reporting in traditionally democratic areas so those areas will have less House Reps. The census is used to determine how many people live in the US per district and is not designed to measure how many voters per district.
District drawing should be non-partisan, using natural land barriers or other objective ways. To allow a R or D state controlled legislature to draw maps for the specific purpose of watering down the other parties votes seems so unconstitutional to me.

The 2012 election provides a number of examples as to how partisan gerrymandering can adversely affect the descriptive function of states' congressional delegations. In Pennsylvania, for example, Democratic candidates for the House of Representatives received 83,000 more votes than Republican candidates, yet the Republican-controlled redistricting process in 2010 resulted in Democrats losing to their Republican counterparts in 13 out of Pennsylvania's 18 districts.[32]
In the seven states where Republicans had complete control over the redistricting process, Republican House candidates received 16.7 million votes and Democratic House candidates received 16.4 million votes. The redistricting resulted in Republican victories in 73 out of the 107 affected seats; in those 7 states, Republicans received 50.4% of the votes but won in over 68% of the congressional districts.[33] While it is but one example of how gerrymandering can have a significant effect on election outcomes, this kind of disproportional representation of the public will seems to be problematic for the legitimacy of democratic systems, regardless of one's political affiliation.
In Michigan, redistricting was constructed by a Republican Legislature in 2011.[34] Federal congressional districts were so designed that cities such as Battle Creek, Grand Rapids, Jackson, Kalamazoo, Lansing, and East Lansing were separated into districts with large conservative-leaning hinterlands that essentially diluted the Democratic votes in those cities in Congressional elections.[citation needed] Since 2010 not one of those cities is within a district in which a Democratic nominee for the House of Representatives has a reasonable chance of winning, short of Democratic landslide.[citation needed][clarification needed]
