clear and simple solution to all of these problems, and that is federal intervention. >> the federal government stepped in during the civil rights era with the 1965 voting rights act. >> among other things, it prohibited states from denying a person the right to vote based on race or color. yet in 2013 the supreme court up ended a major part of that law. >> it eviscerated one of its key components, which was key clearance. the thing about preclearance is that it's before they could implement a new law dealing with voting or a new policy dealing with voting, it had to be okayed first by the u.s. department of justice or by the federal court. >> from passing restrictive voting laws.
