As of the 2020 Census, Delaware has only one at-large congressional district.
Primary Authority: Legislative plans are drawn and enacted by the Delaware General Assembly, subject to the Governor's veto. The General Assembly can override a veto with a 3/5 vote in each chamber. Democrats currently have veto-proof majorities in both chambers. [29 Del. C. §§ 804, 805]
If a bill is presented to the Governor during session, the Governor has 10 days to sign or veto it; otherwise, it becomes law without signature. If the bill is delivered to the Governor during the last 10 days of the session, the Governor must sign or veto it within 30 days of session adjournment; otherwise, it is pocket vetoed. Sundays are excluded from these calculations.
Mapping Timeline: Final plans must be enacted within 120 calendar days following the receipt of decennial census data. [29 Del. C. § 805]
Redistricting Criteria: Contiguous: Nearly equal in population; Bounded by major roads, streams, or other natural boundaries.
PROHIBITED: Unduly favoring any person or political party. [29 Del. C § 804]
