The latest in Maryland

Dec. 9, 2021

On an eventful afternoon Dec. 9, Gov. Larry Hogan vetoed the congressional map that the state legislature had approved earlier in the week. Shortly thereafter, the state Senate and House voted to override the veto, which officially made the map law. Shortly after that, the group Fair Maps Maryland — which has ties to the governor — announced it plans to sue to overturn the map.

The chosen-then-vetoed-then-approved-then-threatened-with-a-lawsuit 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 opted against advancing an even more aggressive plan that would have placed blue Annapolis in the 1st District, making it a pure swing seat.) Two Democratic-held districts, the 2nd and 6th, also go from leans of higher than D+15 to lower under the map.

Our latest coverage

Who controls redistricting in Maryland in 2021?
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).
