As a result of the Voting Rights Act have “outdated” information and in “innefficient” formulas, the decision to find section 4B and therefore subsquently killing section 5 will stand. This is because Chief Justice Roberts has expressed before that he believes that those sections of the VRA are not effective. Also the consesus between the justices that are for the ruling is that the VRA in 1965 was an extraordinary measure for an extraoordinary problem. One of the main arguements for the opinion of the court is that since the 1965 legitimizing of the VRA there has been great leaps in voting discrimination. And for the 4 justices who voted against the decision argued that yes there has been progress but not enough. But unfortunately that arguement is being swept under the rug because of the 10th amendment about states power.
