Maryland voters will decide in November whether to approve a new congressional map that would likely secure Democratic representation in all eight of the state’s U.S. House districts for the 2028 elections. The Democratic-controlled state legislature approved a proposed constitutional amendment earlier this week to place the measure on the ballot.

The amendment, which requires voter approval before implementation, was sent to the ballot following a special legislative session convened to meet the three-fifths majority threshold necessary for such changes. The Maryland House of Delegates approved the measure with a 96-38 vote, while the state Senate passed it 32-13.

The proposed map has drawn attention because it would effectively guarantee Democratic candidates a favorable advantage across all congressional districts in the state. Lawmakers and supporters argue that the amendment provides a clearer and more stable framework for establishing districts for federal elections.

Opponents, however, contend that the revision entrenches one party’s control, raising concerns about the fairness of the redistricting process and its potential impact on electoral competition. Advocates for the measure maintain it reflects the state’s political composition and aims to reduce drawn-out legislative battles over district boundaries.

If approved by voters, the new congressional map would apply to the 2028 House elections, shaping Maryland’s representation in Congress for the coming election cycle. The vote comes amid ongoing national debates regarding redistricting practices and the balance between partisan interests and equitable representation.
