MSNBC reports.  Zachary Roth, the reporter, tried to get conservative lawyers to discuss their views on whether section 2 is constitutional.

Asked via email to confirm that Section 2 is constitutional, Carvin didn’t respond.

Bert Rein, the veteran conservative lawyer who successfully argued Shelby County before the Supreme Court, ruled out a direct constitutional challenge. (“We do not believe that it is unconstitutional on its face,” Rein told MSNBC.) But he allowed that certain uses of Section 2 could go further than the Constitution allows. “It’s all a question of how it’s interpreted in any particular case,” Rein said.
