The Overview

If you vote in Maryland, the way your state legislative and congressional districts are drawn could change under the Election Districts: General Assembly and Representatives in Congress bill (HB 2100), if voters approve it in a constitutional referendum. The Associated Press reported in 2022 that a Maryland judge rejected a congressional map for violating state requirements that districts be contiguous and compact, and NPR reported in September 2025 that a Maryland court struck down the 2022 map over extreme partisan gerrymandering. Democratic leadership said the bill would ensure Maryland was not constrained by uncertainty in its constitutional language. ​

What the Law Does

The law addresses election districts for both the Maryland General Assembly and representatives in Congress.

By the Numbers

Maryland has a total population of 6,206,011, with 4,829,511 residents age 18 and over, according to 2024 American Community Survey five-year figures. The state's racial and ethnic makeup includes 48.2 percent white, 29.4 percent Black, 12.5 percent Hispanic, and 6.6 percent Asian residents statewide, across all ages.

Legislative Status

The bill was sponsored by the Speaker of the Maryland House of Delegates. A companion bill, SB 2100, is from the 2026 session.

The bill's latest passage was recorded on Aug. 4, 2026. Maryland Matters reported that the House was preparing to give final approval to the redistricting constitutional amendment during the special session. Gov. Wes Moore, a Democrat, approved the bill on Aug. 5, assigning it Chapter 881.

Maryland Republicans predicted a legal challenge, arguing the bill could leave future congressional maps open to challenge in neither federal nor most state courts. Advocates and protesters also voiced frustration during the special session. Because the law is a constitutional amendment, it goes before Maryland voters in a referendum before taking effect.
