It's also a massive indictment of our voting system. These guys won by a landslide of hundreds of votes, and only 51 were identified as definitely fraudulent, not enough to overturn the vote. The judge had to make a judgement call that those fraudulent votes were enough reason to call for another election, which is not an ideal situation.
These guys got caught because they got greedy and overplayed their hand. Makes you wonder how many people have gotten away with this sort of thing.
Racking my brain for a possible motive here... Is this just a disturbed person? Could it be anything else? Is this even worth wondering about?
