Maryland’s Democratic-controlled legislature referred Question 3 to the November 2026 ballot during an August 2026 special session, seeking to clarify that state constitutional standards for compactness, contiguity, and natural boundaries apply only to legislative districts and not congressional ones while authorizing Supreme Court original jurisdiction over congressional map challenges. The Maryland Supreme Court’s September 3 ruling cleared the measure for the ballot after lower courts had blocked it, resolving procedural and single-subject disputes in favor of voters deciding the issue. In a state where Democrats hold seven of eight congressional seats and supermajorities in both chambers, the measure faces no significant organized opposition and aligns with party efforts to facilitate potential mid-decade redistricting for 2028. Traders’ 69% implied probability for passage reflects this partisan landscape and the measure’s status as a straightforward constitutional amendment in a reliably Democratic electorate.
