Just as Caesar's wife must be above reproach, our voting system must be above reproach. There are plenty of common sense things officials can take to bolster the public's faith in the system. For example, we should ban electronic voting machines. The real threat to democracy isn't election manipulation but officials who refuse to enact measures that would dispel even the appearance of manipulation.
