You've heard those stories where the odds in a lotto get lopsided right? Well sometimes a lotto game ends up with a flaw that allows an arbitrage opportunity - you can fill out every combination and walk away with a few hundred thousand or a few million. A small group of people spend incredible efforts, seemingly irrationally, to fill out every possible lotto combo... Now imagine that lottery is for president of the United States. Effectively if you can intercept and alter ballots, you only have to change the 'right precincts' to flip an election.
