This weekend, William & Mary will host an impressive symposium with the daunting task of “lay[ing] a definitive academic foundation” for redistricting law ahead of the 2020 census. The topic could not be more pressing. The Supreme Court continues to consider Bethune-Hill[1] and McCrory, is holding Covington and Harris[2] in limbo pending those decisions, and will almost assuredly see the historic Whitford case land on its doorstep soon. In a weekend that is sure to reveal a number of disagreements on critical questions, perhaps all attendees can agree on one thing: “The most charitable thing to say about the current state of . . . gerrymandering law is that it is a big mess.”
Yet, in the background of almost every major debate lingers a conceptual distinction that could help strike consensus across a range of issues: the distinction between “intent” and “basis.” Intent asks: “Why this district?” Basis asks: “Why this person?”
The concepts intersect on the margins, but each plays a unique and distinct role in the “dilution v. sorting” question, the “race v. party” question, and the balance of powers question, among others. Moreover, the importance of this distinction goes beyond redistricting law—it could play a key role in forming a more coherent, simple, and rigorous voting rights framework at a time when it could not be more critical.
In the field of redistricting law, this distinction makes it possible to reduce a complex body of law into a relatively simple table (assuming the Court is willing to adopt both a political dilution claim and a political sorting claim, as I have advocated and as would address the concerns of the Whitford dissent).[3] [UPDATE: Aspects of this table have been eclipsed by more recent developments in the law.]
| Redistricting | |||||
| Racial Dilution (Statutory) | Racial Dilution | Political Dilution | Racial Sorting | Political Sorting | |
| Authority[4] | VRA & 15th | 14th | 1st and/or 14th (Whitford) | 14th | 1st and/or 14th |
| Intent
(“Why this district?”) |
No showing required
Device may violate VRA despite having political purpose |
Device enacted or maintained “to minimize or cancel out the voting potential of racial or ethnic minorities” (Bolden) | Device enacted or maintained to “to minimize or eliminate the political strength of any group or party” (Gaffney; Bandemer (citing Bolden)), or
“to place a severe impediment on the effectiveness of the votes of individual citizens on the basis of their political affiliation” (Whitford) |
No showing required, but relevant evidence to predominance/basis and state showing of tailored justification
Political objective does not change racial basis of sort. (Bethune) |
No showing required, but relevant evidence to predominance/basis and state showing of tailored justification |
| Basis[5]
(“Why this person?”) |
Evidence of racial basis may favor causation finding, if legally necessary[6] | No showing required; but relevant to proving intent | No showing required, but relevant to proving intent | “State has [predominantly] used race as a basis for separating voters into districts.” Miller
(i.e., racial basis subordinates in fact (Bethune)) Burden shifts on showing of predominant basis (Miller, Bethune) |
State has predominantly used political data as a basis for separating voters into districts (i.e., political basis subordinates in fact (Bethune))
Burden shifts on showing of predominant basis (Bethune) |
| Effect (Preconditions) | Gingles Test (threshold showing that device can impair equal ability to elect)
No strict threshold for finding legally significant polarization (Gingles) |
Gingles Test
See Martinez, 234 F. Supp. 2d 1275 (applying Gingles) No strict threshold for finding legally significant polarization (Gingles) |
“Modified Gingles” Test (threshold showing could be Whitford efficiency gap, Sam Wang’s approach, Bernie Grofman’s factors, etc.)
No strict threshold is necessary |
N/A | N/A |
| Effect (Liability) | Totality of Circumstances | Totality of Circumstances
Burden shifts if plaintiff makes prima facie case (Arlington Heights) |
Totality of Circumstances
Efficiency gap is weighty evidence, but not dispositive (Whitford) Burden shifts if plaintiff makes prima facie case (Whitford)[7] |

Below, I explain the basis/intent distinction further, how it resolves a number of redistricting law issues, and how it plays a critical role in preserving foundational principles of constitutional law in our democracy.
