As of the 2010 U.S. Census, Delaware only has one at-large congressional district.
Legislative maps are enacted by the State Legislature. The Governor can veto the plans.
The Legislature can override a veto with a three-fifths vote. Democrats currently have a veto-proof majority in the lower chamber. No party has a veto-proof majority in the upper chamber.
Challenges to the maps are litigated in the Superior Court.
Kinds of Ballot Measures
Only the Delaware General Assembly may refer amendments to the ballot. There is no initiative or referendum process.
