The Brennan Center has filed a brief urging the Supreme Court to keep preclearance.

But Joe Nixon, a Texas attorney who specializes in election law and a former Republican Texas House member, disagreed, predicting a 5-4 decision to overturn preclearance.

“It really becomes an equal protection question, and I think [Justice Kennedy] may have a difficult time finding there is a valid reason to treat some states differently than any other state,” said Mr. Nixon of the Texas law firm Beirne Maynard & Parsons.

The court is expected to announce its decision in June.
