How refreshing to see a Federal Judge acknowledge that they don't have power under the Constitution to determine the method of voting. That is a power assigned exclusively to the State Legislature. As with any other act by the Legislature, the Judiciary does have the power to determine whether the method chosen meets constitutional requirements. If the Legislature does not structure a valid voting system, the Judge can declare the election invalid. In the case of a presidential election, the Legislature would then determine who receive the states electoral votes.
