The entire PURPOSE of the rules is to ensure that no one tries to cheat and commit fraud. Was Democratic Hawk trying to cheat? Was fraud being committed? Would counting his vote have resulted in less accurate representation of the opinions of the electorate?
Rules don't exist just to be followed. They are merely a means to an end, an attempt to give us a fairer and more accurate picture of the views of the electorate, one that won't be distorted by attempts by people to vote multiple times. When the rules get in the way of common sense and begin to pervert their original purpose, actually working AGAINST a fair and accurate picture of the electorate's preference rather than towards one, then it's time for a change.
Agreed. If the rules are not fullfilling their intended purpose then they need to be changed. However, that doesn't mean that they should be ignored until they are actually changed.
