[EM] G-S theorem and random ballot

[Markus Schulze]

Dear Forest,

in the probabilistic context, a single-winner election
method is "dictatorial" if there exists a probability
distribution p[1],...,p[V] on the set of voters so that,
independently on how the voters vote, this method can be
described as follows: Voter i is chosen with probability
p[i] and the winner is chosen from the top-ranked
candidates of this voter.

So random ballot is dictatorial.
