Fact check: When were Delaware's US congressional districts last redrawn?

1. Summary of the results

Based on the analyses provided, Delaware's US congressional districts were last redrawn in 2021 ^{[1] [2]}. However, this answer requires important clarification: Delaware has only one at-large congressional district ^{[1] [3] [4]}, which means there is effectively no congressional redistricting process in Delaware ^[3].

The 2021 redistricting process was conducted by the Delaware General Assembly, which passed relevant bills including SB 199 and HB 335 ^[1]. The new House and Senate district lines were enacted on November 2, 2021 ^[2]. This redistricting cycle was delayed due to the late release of census data from the 2020 Census ^[5], requiring a special legislative session to complete the process.

The redistricting process in Delaware is governed by the Delaware Constitution, the U.S. Constitution, Delaware Code, and applicable federal laws ^[5]. The Delaware General Assembly draws district boundaries through ordinary statute, subject to the Governor's veto, with the ability to override vetoes with a three-fifths majority in each chamber ^[3].

2. Missing context/alternative viewpoints

The original question lacks crucial context about Delaware's unique congressional representation structure. Delaware maintains only one at-large congressional seat following the 2020 reapportionment ^[1], making it fundamentally different from states that must redraw multiple congressional district boundaries.

There is ongoing discussion about reforming Delaware's redistricting process through the proposal of an independent redistricting commission ^{[6] [7]}. This represents an alternative viewpoint that the current legislative-controlled process may not be optimal, though the sources don't provide specific details about when this commission was proposed or its current status.

The analyses reveal that while congressional districts technically don't require redrawing in Delaware, state legislative districts do undergo redistricting every ten years based on census data ^[5]. The Legislature committed to an open and transparent process, including public input and comment periods during the 2021 cycle ^[3].

3. Potential misinformation/bias in the original statement

The original question itself contains no misinformation but reflects a fundamental misunderstanding of Delaware's congressional representation. The question assumes Delaware has multiple congressional districts that require periodic redrawing, when in reality the state has maintained a single at-large district.

This misconception could lead to confusion about Delaware's political representation and redistricting processes. The question would be more accurately framed as asking about state legislative district redistricting rather than congressional redistricting, since the latter process is essentially non-existent in Delaware due to its single-seat allocation.
