I was thinking that an easier way to achieve the same thing would be to

multiply each candidate's total by a random number from say [0.98 to 1.02].

This would blend 3-way (and higher) ties, while the current method will

only blend 2 way ties.

This would also work for the approval with poll case (both for the poll

and for the main election).

The strategy is to vote above mean in the zero info case.

Basically, in the zero info case, the probability of each candidates winning is equal to all the others.
This means that the utility of the election is equal to the average utility of all the candidates.

The recommended strategy is to vote for all the candidates who have a utility greater (or equal) to the
expected utility of the election.

This is not the same as voting for the highest half of the candidates. In fact, if there were lots of candidates
at high utility and one at very low utility, then the strategy would approve all the high utility candidates.

The risk that the low utility candidate would win wouldn't be worth the benefit from picking between the
candidates with similar (high) utility.
