The latest in Maryland

Nov. 24, 2021

The Maryland Legislative Redistricting Advisory Commission voted on Nov. 23 to recommend “Draft Concept 2” as a starting point for the state’s new congressional map. The full legislature will convene for a special session in December to consider the proposal and set the new lines.

The chosen map keeps Maryland’s current balance of power of seven Democratic-leaning seats and one Republican-leaning seat. However, the GOP-held 1st District does become more competitive under the plan, moving from a partisan lean of R+28 to just R+8. (Democrats on the commission opted against an even more aggressive plan that would have placed blue Annapolis to the 1st District, making it a pure swing seat.) Two Democratic-held districts, the 2nd and 6th, also become less safe under the proposal.

The last time Maryland redrew its districts, the final map drew claims of partisan gerrymandering that inspired a lawsuit that eventually made its way to the U.S. Supreme Court. Republican Gov. Larry Hogan has long pushed for a switch to an independent redistricting commission and even created a kind of fantasy league version of one this year, though it has no actual power in deciding the maps. That commission has produced its own suggested congressional map, but the legislature isn’t likely to take that suggestion.
