The Wall Street Journal blasts the Holder Department of Justice. 

…Enter Mr. Holder’s Justice Department, which insists that Texas must add more minority-dominated districts to take account of a growing Hispanic population. Civil-rights groups like the NAACP claim that at least three of the four new districts should be minority districts.

That kind of raw proportional representation has already been shot down by the Supreme Court. In 1996’s Abrams v. Johnson, the Court ruled that similar claims that a Georgia redistricting had diluted minority voting strength didn’t hold water. In the opinion, by Justice Anthony Kennedy, the High Court wrote that when a court is tasked with drawing judicial lines, it “should be guided by the legislative policies underlying the existing plan.”

…As Justice Clarence Thomas noted in his classic dissent in 1994’s Holder v. Hall, “few devices could be better designed to exacerbate racial tensions than the consciously segregated districting system currently being constructed in the name of the Voting Rights Act. . . . Our drive to segregate political districts by race can only serve to deepen racial divisions by destroying any need for voters or candidates to build bridges between racial groups or to form voting coalitions.”

Redistricting has always been a political process, and unless a court finds a violation of law it owes deference to the elected state legislature. The Justice Department’s position is a federal intrusion to elect more Democrats, not improve racial harmony
