The latest in Maryland

April 4, 2022

On April 4, Gov. Larry Hogan signed into law a new congressional map passed by the Maryland General Assembly the previous week. Democrats in the legislature had previously enacted a different map back in December, but a state judge threw it out on March 25, calling it an extreme Democratic gerrymander by Democrats. Hogan, a Republican, called the new map “a huge improvement” and agreed to sign it into law after the state attorney general dropped an appeal of the judge’s decision to throw out the old map.

In contrast to the old map, which created seven blue seats and one red seat, the new map has six Democratic-leaning seats, one Republican-leaning seat and one highly competitive seat. With an efficiency gap of D+2.4, it is also much fairer than the previously enacted map, which had an efficiency gap of D+16. Under the new map, the state’s lone Republican district, the 1st, becomes more solidly Republican than in the rejected map. The 6th District, currently held by Democrat David Trone, also becomes highly competitive, with a lean of R+1.

Who controls redistricting in Maryland right now?
Democrats fully control the congressional redistricting process. New maps are drawn and passed by the Democratic state legislature and signed into law by the Republican governor (but legislative Democrats have the numbers to override a potential veto).
