Redistricting

2020-2021

See also: Redistricting in Delaware after the 2020 census

Delaware was apportioned one single at-large U.S. House seat, making Congressional redistricting after the 2020 census unnecessary.

How does redistricting in Delaware work? Because Delaware has only one congressional district, congressional redistricting is not necessary. The state legislature draws state legislative district lines. The governor may veto the lines drawn by the state legislature.

State law requires that state legislative districts be "insofar as possible, contiguous and bounded by roads, streams and other natural boundaries." Further, state law stipulates that district lines "may not be drawn to unduly favor any person or political party." Because these requirements are statutory, the legislature may amend them at its discretion.
