Congressional
As of the 2010 U.S. Census, Delaware only has one at-large congressional district.
Legislative
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 both chambers.
Challenges to the maps are litigated in the Superior Court.
