Ellen Katz has this essay, forthcoming in the Ohio State Law Journal. From the abstract:

Losers in partisan districting battles have long challenged the resulting districting plans under seemingly unrelated legal doctrines. They have filed lawsuits alleging malapportionment, racial gerrymandering, and racial vote dilution, and they periodically prevail….
This Essay argues that the application of distinct doctrines to invalidate or diminish what are indisputably partisan gerrymanders is not necessarily problematic, and that the practice may well have salutary effects. The focus is on the Supreme Court’s recent decision in LULAC v. Perry, the most recent example of the sort of judicial decision about which election law scholars fret. Unable to articulate any constitutional problem with a blatant partisan gerrymander in Texas, the Supreme Court found traction under the Voting Rights Act and held that a portion of that gerrymander diluted minority voting strength in the southwest portion of the State…. LULAC suggests that Justice Kennedy may find within the Voting Rights Act itself the standard he has been seeking for managing claims of partisan gerrymandering.
