A rare example when a single vote would count

It is often said that turning up to vote is not quite rational behavior, because the probability that your vote would decided the outcome is minuscule. Opponents of such outlook say that it is rational to vote, because you might want to show support for the political system (democracy) or to avoid the regret.

I guess at least one person in Byron-Bethany irrigation district in California feels such regret, because the last election outcome in this district was decided by three random rolls of the twenty sided dice. More details in the CBS video below.
